Hi there. I'm new to the chicken world and currently have four eggs in an incubator (three didn't make it early on). We're on day 22 now and two of the chicks have pipped the eggs 8 to 13 hours ago. One of the chicks has been chirping and moving a bit and the other chick hasn't moved at all in the last 8 hours. The two eggs that haven't pipped yet have also been silent and completely still for the past 8 hours. All four eggs were quite squirmy just yesterday and had been that way for two days. The sudden stillness is making me anxious. Is it normal for chicks that are close to hatching to become very still for an extended period of time? Thanks so much for any information and insight provided!
