I have three barred rock chicks that are about 6 weeks old. A few things: 1. They are still sleeping inside the house. At night right before the settle in they squeak at each other for a good 20-30 mins. It is so loud! Comments about this? 2. One is quite a bit larger then the other two and I often find her sitting on the roost and them on the ground now. This is a new behavior. Previously they all slept on the roost together. Any thoughts on this? During the day they have lots of room to play outside and generally seem very happy. We are moving them out to the coop at night in a few days hopefully.
