My flock is not quite a year old... they were born the end of April. I have new chicks that were born between February 16 - 19th. So they're four weeks old. Anyway I am wondering when I can introduce them to the flock. I don't have a grown rooster right now so no need to fear that sort of thing. My original flock has 2 Rhode Island Reds and 3 Silverlaced Wyandottes. My new babies are 5 female red sex links and 1 male red sex link (who is white and black and gorgeous). I brought the oldest and strongest outside to sit in the grass with me the other day. I put down some scratch for her to peck at. My most gentle chicken came over and starting pecking in front of her and she got the picture. I thought it was oh so cute when my "gentle" chicken pecked my little chick! I was so angry! So now I need to know when I can introduce them and have them not be killed by the others!!
