I have an assortment of 6 BEL standard pullets(?) from MPC. They are 4.5 weeks old and are still staying in their brooder at night. We built an A-frame chicken tractor for our urban environment. The footprint of the tractor frame
is 6' by 7'. The top and sides are wrapped in hardware cloth and have about a 6" skirt all around, secured with weight to reduce the chance of burrowing predators/pests. The enclosed coop is 4' by 5'. Is this enough room for them as they get older? My thinking was that in our mild climate they would be outside most of the time with coop confinement only at night and in inclement weather? I move it about every other day so they will scratch in different sections of the yard. While reading that coop area should be 4 ft per bird, I began freaking out that I have an insufficient space for the girls. Please advise.
