I have some due to hatch on Monday. I'm sure at least half of them will be roos; more if my luck runs true. I currently have 11 three year old LF brahma hens in one coop. The other coop has 16 standards, two banties (silkies) and a polish cockerel. Ages ranging from 14 weeks or so up to age 14 months old. The birds all free range together. I wouldn't mind keeping two of the pekin cockerels. That would give me a total of 3 roos (if you can call the polish a roo, he's pretty much just yard art ) to 29 hens. Should work out, right?
