So my brooder is a 2 ft by 3 ft rabbit cage that I am keeping in my coop. I have 5 babies in it that are almost 3 weeks in it and I have placed it into the coop so that the big chickens who will be 11 weeks on Tuesday so they can get used to them for when they are old enough to go out with the big chickens. It's definitely hot enough with it being 95 each day they almost need a fan more than a light. I only turn the light on at night. Anyway I went to feed and change waters tonight and to put everyone in bed and when I opened the roof of the brooder to get the waterer one of my Cochin mixes hopped out into the big coop with the older chickens. I heard him chirping loudly and one of the big girls proceeded to peck at him and got him a few times on the head before I rounded him up and put him back in the brooder. Thank goodness he wasn't injured but it sure made my heart beat fast thinking that one of the roos was going to grab him and take off for a snack ick. Here is the offending baby lol so happy he's okay. I'm thinking he is a he but I could be wrong he's not very old after all.
