Hi all, just thought id post this as im like a child with a new toy Just got 4 13week old common hens. looks like they will settle in nicely in the shed ive converted to a coop. only thing is, 3 of them went straight into the nest boxes & look like they are hiding. the other one is very forward and already taking food out of my hand. are the other 3 ok? is this normal? also, in the coop there are two windows, shall i cover these up completly or leave a small gap for the light to get in?
