Hi! I downloaded the 19.2 version of your mod yesterday. All aspects of the mod are running perfectly except for the breeding feature. When I try breeding 2 of the horses (Spawned from the egg for your mod, tamed, opposite genders, and with golden apples) they act like they're breeding, but no foal appears. I still collect the experience from it as well. I've tried this with several different pairings of horses. I'm not sure what could be causing this?

That would be the pregnancy feature. Wait a day, and the foal will appear. Meanwhile, you can check progress by looking at the mare's inventory. In the top right corner, if she's pregnant, there will be a little bar that fills up over time.

Oh my goodness I'm sorry, I didn't realize that was a feature. Thanks for the info!
