I would suspect that your hens are molting, which is common in 12-14 month old chickens, and each year thereafter. Or it could be mites/lice. I'd check for small moving black or yellow things on their skin and feathers, and treat if you see any.
Well thank you for the welcome you all. I am from texas so we say yall. Lol. I will be posting some pics of my coop n run soon. I have picked up alot of info and ideas from byc. I catch myself looking at this site more than my fishing sites. Lol
I read an article on chickens molting and one member mentioned to treat the chickens to some BOSS. What is BOSS? That way i can get some or what is it comprable to? Thanks marc
