Tandykins you are free to do what you like with your chickens but that is livestock to me, and livestock belong outside. But as I said that is my perspective on it. You can do as you please in your own house. Why? because I don't have to live there. lol.
Acornewell if your SIL didn't like properly cared for chickens in her neighborhood then she's a fool, and as a 80's country song said. There ain't no fool like a full grown fool, you can talk talk till your face turns blue, but there's no getting thru to a full grown fool.
Thanks for your permission to do what I want in my own house. ^_^ I kind of felt that went without saying.
