I think I could maybe help with two problems, and not help with two problems. There are chicken nappies you can buy from a website, right on BYC. Or you csn make them, which I am sure is no problemo for you since you are maker of curtains for coops, Aye?
I know of no answer to crowing rooster. If he is not to crow, I think the fix may be surgical, but I dont know.
The answer, of course, to your lonesome Rooster, is he needs at least one new female. I am sure with your guidance he will love her. Just get auto sexed female so you know almost for sure it is female.
Maybe problem with your husband will resolve itself when he sees nappies? Good luck I pray for you.
