OR, you could pen the roos in trios... So, 2 girls per boy... or, go and pic up a few more dotte pullets.. like 4 more. Then give each roo 4 girls. I don't know your set up, but, if you are planning to stick with one breed, that would work, since you'd have 2 different roos, each with his own hens, and then those eggs, if you incubate, you could then turn those pullets, (mind, you'd have to know who is who) to the other roo, and any new cockerels, breed to the non siblings... It could be more or less a lot of work, depending on if you can keep track... Oh, I am making my head ache worse just thinking about doing that. LOL. Though I do want to do that with my faverolles and silkies. LOL. My ma doesn't know it yet, but I am sending an email off to Jerry soon, to get me some new faverolles. This week, nothing to pay, except cell phone, and the plan is to finish the summer coop up, move the littles, who are not so little anymore to that, clean and sanitize their coop, and move in some pure faverolles. Yup... thats the plan.
