We put in 6, 6-week old chicks with our existing year-old flock of 8 hens and they were separated for 2 weeks while in the coop together. Then, because we only have one coop and the chicks were getting pretty big, we integrated them together. The chicks stay in the coop...but the door is open for the larger hens to go out into the run. In the coop the pecking occurs, but with 6 chicks and usually only one hen doing the pecking at a time...they can hold their own. But periodically, one chick will go out into the run and with all the hens out there...they will all go after the one chick....it eventually somehow getting out somewhere, or getting stuck in the chicken wire and luckily...I've always been around to save it. They seem to stop pecking it when it stops moving and gets stuck or such. Any suggestions? Do I need to separate them again? I cannot shut the hens out of the coop... thanks!!
