I have five Hamburgs that are 10 weeks old. Two of which are blue/gray spangled and three that are silver spangled. I have one that is for sure a cockrel because his combs are in and his tail is alot longer than the rest. Im just not sure about two possibly three others. When I let them out in the morning he seems to go after one at a time and fluff up his neck feathers and stare at them as if to claim his territory or place in the flock. I also have RIR's which he doesnt bother. So are the ones he is going after males as well??? Or is he just being temermental? Thanks in advance. I will have to post pic when or if it ever stops raining here.
