I don't know what to say about that stupid rooster. He is the best defender and most human-friendly rooster I've ever had. Yet he has 11 hens for himself and he rips up 11 of them. 1 (the one I posted about) is in terrible condition. I'll get a picture of how hurt she is.I'd get rid of the rooster.
I'll look into the sweater. I'm looking into rehoming it.remove rooster or add more females
.....They have chicken sweaters you can buy
I use saddles on some of my girls. I have one hen in particular who seems to be the favorite and always has a bare back and sides if I don't keep a saddle on her. Occasionally I will take it off of her for a day, but then I have to keep her separate from the rooster. She has several, so when one gets wet or too dirty, I will switch to another. She doesn't mind it at all.
