I have four 11 week old chickens 3 are bantam Cochin/ silkie mixes, one a sebright/ bantam Cochin mix and one silkie. 2 pullets and 2 cockerels. I really should only keep one cockerel since we live in a neighborhood but Im having a hard time deciding to rehome him. I'm for sure going to get another pullet, probably a silkie so mine has a friend. I'd like to keep my four and add a 5th just not sure if I have the space in my coop. My coop is pretty tiny only 40"x 40" but they all sleep huddled together in a corner or one of the 3 nesting boxes. The run is 3.5'x12' and then we fenced in a 21'x18' area that I let them roam in for a few hours a day when I'm home. Do you think since they are all small breeds 5 will be too many in the small coop? Advice please!
