I'm currently hatching Sebright chicks in my incubator and two have hatched just fine, (they are on day 21) but the 3rd I'm having some problems with. It seems she's struggling to break through the membrane. It had turned a brownish colour and looked almost leathery, so I moistened it with a bit of warm water in the hopes that would help. She just really seems to be struggling. I found the egg pipped early this morning around 5am. Should I help her out? Just make sure the membrane is moist and let her get out on her own? Any other suggestions? Thank you!
