My 12-13 week old Jersey Giant cockerel (who lives up to the breed name, wow) is kept with 11 pullets. 5 that were from his same group (1 JG, 2 white leghorns, 2 buttercups) that he is good with, and 6 cochins that were added to their group a couple months ago and are 1 week younger. He still keeps the cochins from eating at the same time and won't let them on the top roost. He does not chase and attack them, but pecks them in the head (hard) when they are too close to him. Repeatedly until they leave. I know Jersey Giants are slow maturing....he has only really started trying to crow this week and I have yet to catch him making any moves on his ladies. Will this improve as he gets more "cocky" with age? Or will he always "shun" the cochins? This picture is really dark (bedtime!) but shows my JG cockerel standing next to the smallest (banty?) cochin. The cochin really wanted that top shelf but the JG was pecking him good trying to get her off. I finally moved her myself farther away from him. He is not overly aggressive to them, just does not want them right up next to him eating or roosting. He lets "his girls" do whatever they want. Will this change? Or do I need a cochin roo now? Ha ha ha.
