My main coop thing has a 2x6 coop with a 6x10 run how many will fit in there? They only go in the coop at night to sleep because it get hot where I live. I also have a grow out Pen (open air) so it has no coop. (Actually I do have a small dog house thing that I could put in it but that would take up some of their space.) The pen is 5x5 how many will fit Humanely, because someone said I could fit six, at 4sq per chicken, but I put 4 of my hens in there to graze and it already looked squished. I don't want them to peck each other. I was thinking maybe 4 until 2 of them are big enough to go in the main coop. And I could leave the other two in there permanently, or until I sell them if i decide to (with a coop of course). Will this work? Thanks in advance!
