I just butchered 13 RIR hens because they are not laying well. I did not realize that part of the "not laying well" was probably because they are molting. So, I now have 13 hens with alot of small feather stubs that I could not get to come out (without major effort) I am guessing here...Should I not butcher when they are molting because of this very problem? Has this happened to you? Will they pluck clean if they aren't in molt?
