Hello! I feel like I am posting a question thread on every forum here! I'm looking to build a small backyard coop for 3-4 hens, and would prefer not to spend much more than $100 on materials. It would have to be predator-and-dog-proof and would have to fit in a relatively small area. I really don't know much about coop design/construction and if anyone has any ideas on what type of coop/chicken tractor that could possibly work, that would be wonderful! Thank you!
