My little chooks will be making a move soon but will have to go from free ranging to penned. I would like to still give them space but funds are very limited, I need cheap but secure run ideas and I was wondering how big of a run for 9 chickens and how big of a chicken tractor for the same number. Also is a tractor a good substitute for free-range, will the chickens be as happy as they were free-ranging. I love my little babies and I want to give them the best but I'm just a poor college kid moving out for the first time so like I said money will be a concern. I would love anything any of you can help me with, thank you for your time.
