I've posted once before and I need some clarity.... How many Chickens can I "safely" place in my new coop. I've included a picture so you can see the coop. Dimensions are 8'X3' for the enclosed roost area and 10'X8' for the run. not including the small space under the roost. I'd like to house a total of 20 birds. My current 4 (3 Rhode Island Red hens and my mutt Rooster) PLUS; 4 Black Copper Marans 4 Ameraucana's 4 Jersey Giants 4 Buff Orpingtons Total of 20 chickens! I've set aside some cash to open things up to house more chickens if necessary, the run will be opened up to 12'X12' and the roost (enclosed area) increased to 10'X8'. Do I need to spend some cash or am I Ok with what i have?
