I have 6 chickens, Lohmann hens, and I recall reading about minimum space per bird at a feeder. Twice a day they are fed and feed remains out all day, but I am overdue for a proper chicken feeder. I've purchase the pvc pipe and fittings needed for a pvc feeder, like I've seen on this site (thank you!) as my coop space is limited. However, when I do feed they swarm their feed tray and I'm concerned about fighting. Any comments would be appreciated.
