Some of my hens have ruffled feathers or bare spots on their back, neck, and/or head. I'm pretty sure this is becase of my rooster. I used to have 7 hens and one rooster but a hen recently passed away so now i'm left with 6. The only solutions I can think of for this problem are getting more hens or getting rid of my rooster. Because I dont want to get rid of my rooster really the only choice would be to get more hens but I understand that is a very long process. Are there any more solutions to this problem? And if not whats the best way to introduce new chickens to the flock?
