This is our first time with hatching baby chicks so we need some advice. 3 have already hatched and several more have holes and hopefully will today or tomorrow. Today is day #20. One baby chick is partially out and has been for at least 4 hours. It's still slightly moving and breathing but doesn't seem to be trying to get out very much. Should we try to break a little of its shell? I've heard their feathers can dry out causing them to stick the shell and die. None of the others have taken this long so we're very concerned. Any advice is greatly appreciated! We've been coming to this forum all weekend and it's helped so much!
