So last night I unplugged the heat lamp to my brooder and forgot to plug it back in. A few hours later I noticed it wasnt on so I walked over there plugged it in and look in my brooder hoping everyone was okay. I only have four chicks in the brooder right now. Two are around 4 weeks old- 1 Araucana pullet and 1 Barred Rock pullet. The other two chicks are two week old Speckled Sussex pullets. When I looked in my brooder I saw the cuttest thing EVER!! The 4 week old Aracuana was all puffed up and both of the two week old Speckled Sussex chicks were sleeping under her like she was their monther. Isnt she a little young to be looking after other chicks? Is this normal? Thanks!
