I have not been able to find a good thread/article on chick behaviour and development from week to week. I have 7 mixed breed (copper black maran/amerucana) chicks that are almost two weeks. I am looking for info, about when to introduce roosts, and scratch/dust baths and when to watch for male vs. female behaviours. For example some of them are already chest bumping for status, are these more likely to be male or female? Thank you!
