This chick pipped yesterday, and broke the hole open wide last night. He still hasn't made any more progress! He peeps really loud every once in a while and and does jerky head motions like he's trying to zip but he misses the shell. The egg he is in is kinda small. Could he not be able to pivot to zip? When should I help him? I really want this baby to live. It's a lavender Orpington!
