Well, I bought my first nubians yesterday and one of them is a buck and i plan on keeping him a buck. he is 3 months old and i was wondering when he needs to be seperated from my 2 pygmy girls and the doe i got with him. also, once seperated, does he need a buddy? or will he be fine if he can see the girls in their pen? my second question is how big of pens do i need to build for the goats outside? i have 2 pygmy does and a nubian doe (shes little now, but will be a big girl) and then i'll also be building a pen for a nubian buck and possibly a friend depending on answer to first question. i will also be building them shelters outside, how big do they need to be? third question, when is it ok to breed the nubians? and also, (dont' freak out if this is a stupid question, but i really don't know) can the nubian buck breed the pygmy does safely? or do they need a buck their size?
