I have 14 5-week-old chicks in a brooder. Until today, they have all got along without any incidents. Two of my chicks had pecking wounds, one pretty significant. I blue coated them and put a red light on them, and waited and watched to find out who was the culprit. Didn’t take long. One fiesty little chick ( the smallest one) was running around pulling everyone’s feathers out! I separated her. How long should I keep her separated? Will it help her behavior? I will not be able to move them to a larger space for another week because of the weather.
