I have baby chicks.. 16 of them. They are 5 weeks old and in the outside coop. It is 8ft x 8ft. My Welsummers seem to be growing slower than the others and are also missing feathers on their backs- like they are being picked on. I have 4 austra whites, which I believe to be the culprits. I have had leghorns in the past- so I know their demeanor. The austras also seem to be the more confident of the group and one of them was even sparing with the baby cakes treat I put in there .. but on a more serious note- these should all be pullets. They came from Cackle Hatchery- I am just concerned that the Welsummers are supposed to be a heavier bird, but are growing slower and being picked on. Any remedies? They have enough space and I gave them treats to keep them occupied.... I feel bad for my poor Welsummer babies and they are looking kinda rough.
