Trying to see if there is anyone out there from extreme Northern Maine. We are still snowbound, although there are finally spots of grass starting to show up in between the large piles of snow. I'm trying to convince the wife to let me put a few hens in the open space in the garage (back room). Two questions - are hens loud? as in, will they bother the neighbors? and how much outside space would be necessary for four or five hens?
