I have a two week old Polish chick and a week-and-a-half old Easter Egger in my feathered family of 8 who are absolutely inseparable. We bought them two days earlier than the 6 others, so they had the brooder to themselves at this time. Now that the brooder is full, Henrietta the Polish and Artist the EE are still attached at the hip. They eat together, they drink together, they nap together, and they follow each other around CONSTANTLY. If you pick up one, the other will peep loudly looking for her missing sister. It's the most adorable thing I've ever seen. Do chicks this young form friendships or attachments with each other?
