Cowpoke
the barns are programmed to allow the animals in them to breed without a incubator. The coop is programmed so all animals in the can only breed using the incubatorMy counter to this is that ostriches are a barn animal and do require an incubator. If it can go one way, it shouldn't be too difficult to go the other way.
So the ostriches breeding without the incubator is all due to the barns programming
Which is why the bunnies need a hutch, because they dont produce eggs
