I have a White Plymouth Rock who has been broody since December 27th. How long do they stay broody? When she get's off of the nesting box the other chickens attack her. Is that normal? What about her behavior? She ruffles her feathers and crown and growls at the other hens, and she acts very frantic. Normal? She was also a very large bird and is getting thinner. How long will this go on? Moving on, I have 11 hens (1 Leghorn, 2 White Plymouths, 2 Ameraucanas, 3 Barred Rocks, and 3 Rhode Island Reds). Recently, the Rhode Islands have turned nasty. They have been attacking some of the other hens. They have always been more aggressive to my white hens because they weren't the "original 8". Now they are just getting nasty with them all. I was thinking about getting a rooster so he can be the bossy one. Would this be a good or bad thing to do. Love to hear your thoughts and opinions.
