paddock size, plant variety, figuring how many animals

I am plotting, er ahem planning , for some sheep. I don't have the ok yet but will add pics of the area that would be turned into paddocks, it is about a 1.5acre. I am in SE/central Ohio. Plenty of rain pretty much always and plenty of snow in the winter. I have lots of experience with goats and have been reading up on sheep off and on for a handful of years.
My prospective herd would be a few wool wethers and hopefully a couple ewes to breed for meat lambs. Breeds: definitely Shetland, very likely Icelandic and crosses of. I am open to others and crossing to a hefty ram for meat lambs but it will depend on what comes up locally.
The area is almost entirely overgrown and I would start off by mowing a path and fencing one paddock and putting a couple goats in to grow up and eat a lot of the junk down. then go in and start chopping and the worst of the stuff. I want variety but there is a lot of bushy and unusable stuff there now. Then I would mow another path and add another paddock next to that one and move the goats. depending on how bad the first paddock is then I may have someone brush hog it so I can do some proper plants growing.
The land has variety of plants I know. There is for sure: timothy, giant red clover, wild blackberries, multiflora rose, hogweed (wild amaranth), lambsquarters/jewelweed, wild clover (small white flower), plantain, dandelion, poison ivy, wild strawberry,.....
I want to definitely get out the multiflora rose and the poison ivy. its such a huge pain. theres a lot of other weeds and things I don't know the names of. theres a couple trees on the area. I know a couple are younger black walnuts and I want to take those out, they are EVERYWHERE here and a huge pain. I think some of them are 'tree of heaven' (Ailanthus altissima) which is ironic because the leaves and cut wood smells nasty. I want to take them out too, they grow a lot in clumped grove like spots here.
In the paddocks I thought of planting in with the exsisting: a little alfalfa, oats,..? Suggestions welcome. It's raining today but I will try getting some close up ground pics to try and show grass/plant variety.

After I got things going I would like to rotate the paddocks with the goats, followed by the sheep. I think the land can manage a fair density of animals from my experience here already with the dairy goats. I will be starting small and growing the flock over time so I can manage the paddocks accordingly. I hope to rotate them every three days and think that I can do five good size paddocks plus one that would be my 'yard' area with the hog pen and rabbit building. I feel like with my current knowledge this could sustain two dairy goats, four wool wethers, two breeding ewes and their lambs.

From the silo over just past where the edge of this pic is.. down to the road, just out of sight in the second pic, its actually down a steep bank from the usable area..

this pic shows better the full width. you can see the top o the silo there. and that's IBC water totes if that helps size reference.

here shows the farther part of the downhill half.

I don't know about Shetlands, but my Icelandics will eat nearly all that brushy stuff, including the multiflora rose and the poison ivy. They're helping clear my overgrown pastures!

Shetlands like a variety of "browse" like you have in those pictures.

I don't know what you mean by using a "hefty" ram on your Shetlands to get meatier lambs, but I'd be concerned about that. The average adult Shetland ewe is only 80lbs. Breeding her to a larger breed ram is asking for trouble. I know someone that bred her Shetlands to a Friesian ram and she had so many lambing issues.

I love my Shetlands. They are a fun little sheep. I would highly recommend halter training and bucket training them. Handle them a lot.

thanks. I had three angora goats for under a year and seriously had to scour a 5acre pasture for one and cut it from the ground because it got tangled in a bush and was tangled all up down to the ground. I thought I had picked all the sticks out when I got her up but when they were sheared she still had one on her neck that had rubbed a spot raw ): So I am aiming for at least hugely reducing the amount that grow in the paddocks but since I wont be digging up the big stumps I am sure some will grow back.
the poison ivy I do want to eradicate in the paddocks because I am a handspinner and don't want to get it any more than I usually do! Since I wash my own fleeces mainly etc. I have gotten it plenty of times from milking the goats as it is.

Thanks for the input. I wasn't sure if I should really plant anything into it more or not. I am sure once i get into things i will see if any nutrients etc are low and plant things to help that way. which reminds me i need to price loose mineral that don't have copper /: When i had stopped in TSC the blocks all had copper and the couple loose mineral all had copper and only one of that was small as 50# bag, i really don't want to start with a 100# tub of loose mineral!

ok if I do a 3-day rotating then it will be 15 days.
day 1, 2, 3: goats pen 1, sheep pen 4
day 4, 5, 6: goats pen 2, sheep pen 1
day 7, 8, 9: goats pen 3, sheep pen 2
... etc etc it will be day 16 when the goats go back into pen 1. I think at first I will have a lot longer time on each pasture when I start. since its a lot to eat down starting off and I will be adding paddocks over time, less paddocks to go through and less animals to eat through it. but once I get the flock built up I can definitely see a 3-day rotation working well. maybe quicker even depending on how the land grows back once on the rotation.

Each paddock will have a three sided shed shelter. On my yard section is an existing hog pen. Additionally I would be adding the rabbit hutches and possibly a chicken coop. the chicken coop would go on the back of a small barn type building that I would keep the goat and rabbit feed etc and hay storage plus a small section as milk parlor for the goats and possibly tryin out milkin the sheep later on. Around the yard area would also be garden areas of different plantings.

I have an idea on playing with adding swales in the paddocks. I probably wouldn't be able to add them right away so depending on time they would be added after all the paddocks are setup or the later paddocks area would have swales built before they would be fenced and the earlier paddocks that would be fenced first would have swales built in them after fenced.
podcast the idea was from (around the 1:00:00 mark): http://www.thesurvivalpodcast.com/tag/sheep

I am doodling a probably-not-really-much-to-scale outline of the setup I would put the area into. later I will hopefully make it prettier and readable and try to post it.

Ok I managed to figure out how to snag and edit an aerial view. the hill is somewhat west facing, right of the pic being east and left of the pic being west. not exactly straight that way but close enough. the pics I posted before this are taken from the spot between my doodled paddocks. theres a tractor lane going up from the road to the silo you can see in the pic, that's one boundary line. the other is my somewhat-straight-ish paddock fencline toward the bottom of the pic toward the barn area.


plants that I IDed in this area today:
queen annes lace (wild carrot), mullien (cowboys toilet paper), poison ivy, wild black berries, black walnut trees, thistle, nettles, wild amaranth (pigweed), white clover, red clover, dandelion, wide leaf and narrow leaf plantain, purple deadnettle and/or henbit, goldenrod, pokeberry (these are everywhere here and poisonous I know, goats would never eat em anyway), burdock (dock, burrs, etc),...
And I finally got an ID on one that I have been unable to name for years /: unfortunately though its Horsenettle (Solanum carolinense) and I will have a heck of a time getting it out of there. its poisonous and in the nightshade family.

I would skip the wether and just use the ewes for wool. That way you get more lambs that you can sell and use to pay for their feed and such. So instead of 3 to 4 lambs from 2 ewes, you could have 9 to 12 lambs from 6 ewes.
