I don't "do" roosters. I just don't want to deal with the potential pain in the neck or the drama. I have a riding academy and lots of kids come and go, and although the chickens are locked up, it is conceivable they could get out. To help against this happening, I have trimmed one wing on each of the chickens. Back in April, I received an order of 15 pullets from Ideal, and a friend of mine (science teacher) gave me his 6 EE's that she'd hatched out in her science class that are the same age. Everyone integrated well, no problems. This week, I've heard definite crowing!!! It looks like three are roosters. They are 22 weeks old now (no-one's laying yet) and they all still run away from me when I approach. I don't mind having them if they're not mean, but if they're mean - they're outa' here. Pronto. At what age will I begin to see aggression develop? Will I have better success keeping all three roosters or just keeping one (fertility rates are not a concern for me). Is it guaranteed that they will become aggressive?
