I bought some new hens the other day, 1 glw, 1 leghorn x araucana, and 5 isa browns. The glw and the isa browns are very feisty, and all the hens bar the leghorn x have bald sections. The place they were in before was a lot smaller than my run, so I was hoping it was a lack of space issue that could be resolved over time. I currently have 5 chickens in my run, and the new 7 in a separate quarantine pen. So once quarantine is over, they will be moved into the main chicken run. This is a photo of my run. At the moment I have one nesting box (quite long, has multiple entrances) and a large dog kennel for sleeping in. I know I need to get some extra housing up before I move the new ones in (and have one underway), but I just wanted to know if it was actually enough room for all 12 hens, or whether I should increase the size of the run? I originally thought it was okay, but don't want to give them any excuses to continue pecking each other! I know the photo isn't that good quality, my apologies! But hopefully, with the chicken and pekin duck in the pen, it gives a bit of perspective. From the side to give an idea of width. I would guess its about 2.5-3 mtrs wide?
