We are in the final stages of building our coop (I'll post pics soon). We have 4 girls with a 4' x 5' coop, and they'll have an enclosed run. I am confused about which feeder and waterer to purchase... what size do you prefer for a small backyard flock? I also think we'll want to hang both the feeder and the waterer... am I correct? I didn't realize that our local feed store doesn't carry a large selection of poultry waterers and feeders year round, so I am going to have to order online. Any suggestions? Thank you!
