I have a new chicken that I tried to introduce to the other four girls yesterday for about 45 minutes in the yard. They all bumped chests with her and pecked her a little bit and then they ignored her. So, I am going to do it again today. How much pecking is normal to establish order and when should I remove her? I don't want to interrupt the process - but I also don't want them to hurt each other. Ya know? Fine line....I hope they all get along.
