Hi there! so looking for some advice from those with more experience. I have 6 chicks who will be moving outside in the next month or so. We are trying to put together a coop and run as frugally as possible. We have come across a metal structure that we could use as our permanent run. It is 10 feet wide, 12 feet long, but only 3 feet high. It would have chicken wire or hardware cloth around it to be predator safe, and it would be attached to the coop. This would be our chickens only run, we can't free range here due to predators... so I need to know if chickens can be in a run that is so low? Do they need to be able to fly/flutter around? Do they need height to be healthy happy chickens? Thanks! The structure is at the end of a neighbours driveway.. so i need to act fast to pick it up if it will work - so any advice would be great.
