I have a chick trying to hatch, who appears stuck. He's peeping, resting, and struggling to break free... but could he be "shrink wrapped"? Should I assist? Its only Day 21, and he can breathe just fine. He's about 90% out, but, again, seems to not be able to break free of the shell. I increased the humidity to about 80% in the bator... it had come down to 70% earlier this evening. He's one of two shipped eggs to have made it to lockdown... no pips in the other one yet. This one seems to respond to video of peeping chicks. Should I play it continuously, or will that over stimulate? Please advise? I took a video but I can't get it to upload.
