So I finally got home to the USA and I am ready to order my chickens, I know it is a little late in the season. Anyway, we have been using my mothers backyard coop as an experiment and I have decided that what she has is simply way to small. She has 4 square foot per bird in the coop and that seems just fine as they only sleep there but the run just seems too small. The run is about 8 square foot per bird and I know the recommended is 10 but even that seems like it might be a bit small. We do free range the birds we have for about 4 hours on week days and all day on the weekend but still, I feel bad for the birds. I had planned to get two breeds of chicken and keep them in separate coops but I think I will skip that this season and go with just one breed and build a bigger coop. With the new dimensions that I came up with it will ramp up the square footage to about 16sf per bird. That is double the 8 my mom has now, will that be a significant improvement or am I going to have to go bigger to see a noticeable difference? So, knowing that 10sf per bird is the minimum standard what does everyone else consider a good number to make my chickens comfortable? I want to go quality over quantity here which is why I have decided to scale things back in the bird department. Thank you in advance for any info or experience you might be able to share.
