Hmmm. So how many chickens can I fit in a 8x17 coop? (They free range every day.)
The back side of the coop
The other side.
Right now they have two nesting boxes but my husband is building a two level set with 4 on top and 4 on the bottom.
Edited to say: We have 11 chickens right now and 7 Bielefelders that are coming in March.
Depends on how good you are at playing Tetris. If you stack them right, you can get a lot of birds in there.
Serious answer, I have an 8x15 coop that I've had 30+ birds in. They have a 16x35 pen attached, but I let them out to free range regularly. No stress issues with them.
