I have 9 older hens, and 9 chicks. 3 Ameraucanas, about 6 weeks old are still in the brooder, as they are still fairly small. The other 6 3 Dixie rainbows (they are HUGE), and 3 black Asians around 8 weeks old. The 6 older chicks are in a separate coop right next to the big hens. The door has a chicken wire window to be able to look at each other. They are getting pretty big, and I'm not sure how to start mixing them together. The 6 older ones I feel like they are almost to the point of being able to go in the coop with the big hens. But the 3 smaller ones I'm kind of worried about. If I mix the 6 with the big hens I can move the 3 smaller chicks to the separate coop. The part I'm worried about is will those 3 be picked on because it took them so long to be mixed with everyone else?? Also when should the 6 bigger girls be mixed with the hens. Any advice you can give me would be appreciated!
