This year, I purchased several baby chickens from one hatchery. Of the chooks, there are 5 or so roosters. I had planned on keeping one of them figuring that I have 3 pullets of the same breed. Then, after reading a post, it occurred to me since I got these all in the same batch they could be brother/sister. So now I'm not sure whether I should keep any of these roosters or not. What do you think?
