I know a few others have posted this question However I don't want to take away from their advice. So here's my set up! We have a 4X4 house that is tall enough for me to stand up inside (I'm 5'2") with about 3 different Roost spots (soon to add more higher up), and soon to be 3/4 Nesting Boxes. The nesting boxes will be a additional box added on to the side of the coop so it will not take up any space on the inside living area. the run is about 6ft long 4ft wide 5'4" tall. But they are only left in there when we are not home. So basically everyday they are free range out and about the yard and in with the goat in their pen. I just recently fell in Love with the Cochin Breed. I have Little Blue cochin roos and want to eventually do breeding. But I don't know how many chickens I can house in what we have... Here are a pic- a Side view of the run and the house (the fence is leaning over one side because it was so Hot out and there was no shade for the the chicks we have currently) Thanks in advance!
