Ok so my coop is 17.5 ft x 11.5 feet and my run is 20ft by 20ft. I am worried I will have to expand and right now I have 27 chicks in the brooder. The coop I am using is the remodeled front room of a old chicken house that hasn't been used in years. I have plenty of room to expand both the coop and the run if I need to. I am also looking for someone to sell me two silkies so they will go out with them also. So I guess what I really need to know is...Will 29 chickens fit in the housing area I have for them.
