I have 7- 3 wk old chicks and when I went to check on them I noticed blood and the whole tail missing from my EE. I separated her from the others and put some antiseptic cream on it. Tomorrow I am moving the chicks into a larger brooder in case that was the reason. I have also been using a red light. Is there something different I should do? Also, how long should I leave them separated? she hates being away from her sisters but I don't want them to peck her. On a separate note... My chicks have the majority of their feathers and it is in the 80s here during the day with the lows at night being in the mid sixties. I have been taking them outside for an hour or so everyday. When can I move them into their coop?
