At this time we have 2 Roosters 10 hens and 2 ducks, we think a drake and a hen. I know 2 roosters is to many, but what is a good ratio? We will probably be takeing the aggressive roo to a friend and I thought about getting a few more hens from him if we can if that helps even it up better. How do you introduce new hens into the flock? Also our crew has a run but of coarse they gobbled all the greenery down to nothing,lol. They do gets snacks and greenery every day, its nice to have some use for all the weeds! Would it be better to cover the run with sand or let it be? Thank you!
