I have two mini lops that I weaned about a week and a half ago and they were fine with eachother. But then a couple days ago I put a baby from another litter in there, they are all the same size but different colors. The two sisters that i weaned first started fighting and it was bad they were on there sides ripping eachothers fur out kicking eachother. So I took the baby I was just starting to wean out and put it back with its mom, and I seperated the sisters. But today I put the sisters back together and they were fine with eachother just eating and drinking fine. I need to wean the other litter. I only have one growout pen right now. What should I do? The older does are just now 2 months and the other is 8 days younger.
