I have 5-5month old silkies 3 roos 2 pullets, 2 MF, 2 RLRW, 2 BR (not sure on sex yet) and 9 RR roos sent as packing peanuts all are 8+ weeks old and 10 mix breeds hatched 4 weeks ago. My coop is 8' long 3 wide and 4 high. I have 3 perches at different heights and 6 nest boxes in the coop which is in a 12x12 covered dog kennel. They all go out of the pen during the day when I'm home. I think I have too many and want to cull the 9RR and perhaps the 2 silkie roos. I feel bad about the RR's, are they too young to eat? Now cold weather is coming. Should I just keep them all until they get bigger to provide heat in the coop for the others? They all seem to get along with the occasional pecking order episodes. Any ideas?
