My broody hen was sitting on 5 eggs. Yesterday I noticed that one of them had pipped, and by the time we went to bed it still hadn't hatched all the way. When we got up it was out walking around. When we went to do our shopping at 2pm today, another one of them was pipping. When we got back at around 7pm, two more chicks had hatched, and the last two eggs were pipping. In the 3 hours since then, no progress has been made on either egg. Is that normal? Should I just expect for them to be hatched in the morning?
