Im super late but i was breeding donkeys and I was in the process of breeding pink donkeys, I only have one purple one since the other died and strangely a pink baby donkey spawned?
I moved your post out of the old thread it was in, as the thread was too old. Better to start a new one.
Also, it appears you posted before your image had completely uploaded. You can edit your post to fix that. The pencil icon is the one to use
Welcome also purple donkeys on some occasions can give birth to pinks it’s very rare though
Not certain but it’s less than 20% I believe
