Ok, is the 55 sq. ft. include the outdoor section? Where are you located? Do you have heavy/cold winters? You will need at least 4 sq. ft. inside if they can't get out during winter months. Otherwise they may beat on each other badly. Also, if you order chicks be prepared for an "extra" surprise
. It's better to have more room than not enough.
We built a tractor with 20 sq.ft on the inside. We insulated it, and shingled the roof which added a lot of weight and so it's a beast to move. We have decided to keep the tractor where it is for this reason. So pick a good spot in case you run into the same issue. I would put it where it's protected from elements, and shady in the summer. The inside of a coop can heat up pretty fast and stresses the hens out.
As far as inside. You only need one nest, and at that an 10"x10" area is big enough you could probably do a bit smaller if needed, people use many things for nests. You can build a box or even use a milk crate filled straw. You can get that from your local store. They will roost at night so you should put one inside. Underneath the roost you will find piles of poo so make sure these piles are not going into food, nests, or water and easy to reach for cleaning. The roost should be off the floor a bit. I would say at least 8 " off the ground. I know there isn't as much room in a tractor so you'll have to be creative. I am hoping the picture I have of our feeder we made for the inside comes though. It takes up no floor space and eliminates the mess. We keep it on the door for easy access. We used PVC piping and parts to make it. We cut a section out for them to feed through. It's worked out great. But I would use a pipe that is at least 3"-4" diameter. You'd be surprised how much they eat!
What breeds are you getting?
I hope this has helped. you.
Good luck.
