Hereās an evaluation form for chicks I found at a
Buckeye breed site, but I think it would be reasonably applicable to other breeds. Itās not going to apply to rooster performance but it should help you choose a chick with the potential to be a good physical specimen.
Choosing a good rooster will take longer than just waiting until the males reach sexual maturity. Young roosters often start out being really rough on the girls becauseāI donāt knowāthey donāt know any better? Theyāre so hormonal they canāt help it? There may be no older roosters or even older, experienced hens who know how to put overly randy roolets in their place?
Iāve found that the boys do settle down after a while, but I can keep as many roosters as I like for as long as I choose. You can have one (which is one more than most backyard flocksters can get away with keeping). Keeping all your males long enough to (hopefully) make an informed decision on temperament just doesnāt sound very feasible in your situation.
I think Iād go with one (or two at most) that looks to have the potential for being a good-lookinā studly stud. If he turns out (after giving him time to settle in) to be a jerk, get another rooster. Theyāre not exactly scarce.
