Howdy!
I am relatively new to this whole cow thing...kind of

I have raised Onon:Ta (Mohawk Indian for Milk) since she was about 3 months old. Her brother, too, but he went to the freezer

Anyway, she is a full size Jersey/Holstein heifer. Sweetheart of a cow, I call her my lap-cow...her brother was a lap cow too. I believe the temperament of the beast is all about how you raise them...the more you are around and love on them, the nicer they are. Mine is/are spoiled to the max, like all critters and "uprights" here on my mini-farm, probably more than needed.

I have Onon:Ta bred to a Mini Hereford, due here in about 2 months...YEAH!!!:bun and I can not wait!!
Here is all I know about the general info on minis: 1 full size cow = 3 to 4 minis when it comes to grazing area. Minis give less milk per day than full size...important when it is just for the family and you don't want to mess with the selling of milk. and of course they are smaller, so barn size varies...
and the meat aspect would be much more "do-able" for a family...instead of having to mess with selling extra. a full size cow can take over a couple large freezers...and with being ably to breed once a yr, with 9 mth gestation, etc...that is appx a cow a yr to the freezer...
yeah, not much. but worthy info! They are VERY expensive to get mind you...which is why we started with the full size...and then I find out it is 16 generations later to get a true mini...ug, BUT the "ride" has proven to be very fun!!
I am currently growing my own hydroponic fodder...basically barley/wheat sprouts to feed for richer, more milk...and cuz my girl is preggers and I want her to be as healthy as possible. I am doing it manually (there are systems out there that I dream of!!!) and it is a HUGE pain in the butt...but it is an experiment, and it is not like I am not here to do it

so we will see...it is very beautiful and tasty though.
Good luck to you and if you are anywhere close to the E. TX area...we will have our first "half-mini" up for sale within the next 4 to 6 months ( we want to offer a less-expensive alternative to family cow stock than the true minis or the huge full size...what could be better than the "in-between"??)
