Mix some molasses with corn meal and a little flour make a small "meatball" then mix the copper rods into the meatball The goats will eat this with gusto and it is a no fuss method. Be aware that they will be looking for more.
Get some Murry gingersnap cookies she won't be able to resist them, only 1-2. She will come looking for them when you are around. They have a great use to give worm meds to goats as well as donkeys. Donkeys can be very loving but it takes time, she has to trust you first. Visit her often so...
Don't chase them as that makes the trust issue even more difficult. Try having a bucket with some sweet feed and see if you can get them to come. If not just place the bucket on the ground and step way way back... They will know you brought it when they are done just pick up the bucket and go...
minus 10 is cold ...I have llamas and do not blanket them but here in NC it will not get that cold. So on the coldest days it might be a good idea to blanket them. Watch for impacted ice in the hooves.
This has to do with age and responsibility ....you see the outcome if you get hurt so the fear creeps in. If this horse is kid safe then go slowly and get up and ride, your fear will subside after a few short rides. Enjoy him!!
Get a feed that is specific for llamas ...sweet feed is not good for them. Feed them a good quality hay and if you are getting 2 llamas you will need about 1/2 acre minimum for them to roam. Good luck!!
