If you feed animals wheat, after they have produced baby they will not be reactive to wheat until they are ready to breed again. Justin mentioned that animals will spawn at our location when you purchase them. Did you spawn animals before you had a containment area for them?
You need a fence. at least 4-6blocks high. for some reason when the server lags (rarely) sometimes animals 'jump' managing to jump 2 and sometimes 3blocks high... hope this helped -echidy
I encountered a similar problem. I purchased a mooshroom (yes that's their name) and it managed to jump my fence. I kept it inside, but had to scramble to make more fences. If this bug could be fixed, it would be greatly appreciated, as I am not a fan of losing 350 rupees.
