We have two 4week old Gold Stars (Nugget and Curry) and the other day we got a 2week old black or blue silkie (China)! Today I was sitting in front of the coop of the big girls and had my silkie in my lap. The girls seemed very intrested and my silkie jumped into the coop with them. One of my older girls, Nugget, ran up to her and pecked her, not hard. The silkie jumped around and pecked her back and then jumped on her. She is such a little snot!! How old should my Silkie be before I put them in together? China seems so lonley by herself, when ever I leave she runs to the side of the box and starts chirping at me and continues for awhile,but I don't want any of them to get hurt by putting them together to soon. Thanks!
