@aart post again. Just because they are free ranged that doesn’t make it ok to crowd them inside. They will fight for space. Someone will get hurt. Or worse. I’ve been there making that mistake. aart taught me so much. 4sqft/bird is only indoor space and doesn’t include the nest area. More room is even better. Roost space is minimally 1 foot per standard bird, more for Jersey Giants! The roost needs to be at least a foot away from the wall unless you don’t mind cleaning poop off the wall every day. It also needs to be higher than the nests or they will sleep (and poop…all night long) in the nests.
Believe it or not there are occasions when you will need to lock your chickens inside the coop. Perhaps a fox starts visiting the area. Until he is dispatched you need to keep them inside to be safe. How much snow do you get? I’ve had to keep mine in until I could reach them after 3 feet of snow fell. And then had to remove the snow from the run. It helped me that they could stay inside a couple days. What about a catastrophe? That’s anything negative that happens that you never would have foreseen. A tree fell over my run. Until the tree service could come and remove it they had to live indoors. My point is space indoors is not an option.
On a different point, the cat jumped into the run? I didn’t realize you had a run since you said they were free ranged. Maybe I misread it. But if the cat can jump in so can any other critter in the world. You’re keeping chickens corralled in one place but not keeping hungry or hunting critters out. This includes hawks, owls, and anything that can climb.
I’m not trying to be harsh but I remember aart being hard on me for my lack of chicken knowledge. Not mean, just firm in letting me know where my Naïve arrangements were inadequate. It was what I needed. I was able to readjust and then it was so much easier to enjoy my chickens. Best of everything for you and your feathers friends. I’m quite jealous of your Jersey Giant!
