Hey guys, I'm trying to make some compact farms on my world and I can't get any of these guys to breed. It's set up with them standing on a half slab that gets water logged by a dispenser and the fence above them. I only have 2 of each in each because I figured that would be enough to get started. I have cows, pigs, rabbits, and sheep (I've got a slightly different plan for my chickens). Any advice is much appreciated as well as tips for expansion also appreciated.
