Yesterday morning was day 21 for our 6 eggs to be under our buff orpington. I found one of the chicks hatched and two eggs were pipped at 7 am yesterday. One of them hatched some time yesterday evening. The other one doesn't seem to progress. The pip barely got bigger. We can hear the chick inside. Everywhere I read it says it takes 12-24 hours. It's been 25 hours now. Do I need to help or keep waiting? Thank you!
