Nipping at rear, not able to poop. Anyway to help?

Oh my gosh, the coconut oil worked!! Thank you! I poked some of that down with electrolytes. Her feet were cold and blue, which I now know from chickens is circulation. So after I poked oil down I researched some leg stretches for chickens and made her do those off and on. Aldo tossed her up in the air and caught her to get her moving. For a relax I massaged coconut oil into her dry feet. Lots of making her stand on her lame side and not using her wing as a crutch.

The result is she pooped on me this morning! I've never been so thrilled to be covered in crap. She's also a little perkier this morning. No more nipping at herself! Thank you thank you thank you!

Pretty sure she hates you all, though. She didn't like flying.

I want go know when I open incubator lid can I open incubator lid during hatching day 21 or wait until all chicks hatched ?
