I have two coops/runs separated by chicken wire fencing both inside and out. One side has only bantam cochins consisting of 2 boys and 4 girls (12 weeks old). The other side has 12 large fowl (various breeds) ladies. Seven are older (2-4 yrs old) and 5 are young (14 weeks old). My two cohin roos are beginning to try to mount the ladies and they aren't having it. I thought 12 weeks was too young bur Tank is crowing and Thunder who is second in command is also feeling his oats but not crowing. I guess Tank is the only one allowed to crow but apparently both feel they can have at the girls. I fear that with only 4 girls, the boys are going to run them down constantly. Should I move one of the roos to the "Big Girl" side or will they be too big for him? Should I try to get more little ladies for the boys? Your thoughts are appreciated.
