This is my first incubator hatch. I have a bantam that pipped 24hrs ago and zipped half way overnight, but I don't see a beak up to the egg anywhere. I though pip to zip was supposed to be 24hrs max. How do I know if I should assist with the hatch? How long should I wait for her to finish her zip before I go in and help? Also, I have a one week old full size chick and two bantams that hatched yesterday. Can I combine them in the brooder or is the ameraucana going to bulldoze my teeny Mille fleurs?
