No baby animals.

[villadaysi]

My animals aren't making any babies, I give them wheat, then they start kissing and xp comes out but no babies? This has happened to all my animals even my dogs. Has this happened to anyone else or is it just because i have to many mobs in one area? I think the removed entities thing has something to do with it but I don't know anything about that stuff? Please help my animals have babies so i can butcher them and sell it at the market.
