Chicks born June 14 & June 25--We're stilling feeding them in the "chick" feeders (two of the red plastic/one of the long metal). When do you normally transition to the "big" chicken adult-type feeders? Or, maybe a better question would be when do you take the little chick feeders away from your flock of chickens? Do you have a favorite store bought adult chicken feeder? (We've been looking at the homemade feeders & there's some really neat ideas.) We bought one hanging white plastic feeder that is supposed to gravity feed with the little dividers in it, but it doesn't work with the crumbles too well. . .you have to turn it and shake it to get the crumbles down where the chickens can eat them--it's annoying. We liked the idea of a hanging feeder to keep the junk out of their food. Looking for suggestions on quality feeder or feeders that actually work well with ease of flow of the food, capacity to hold several days of food for 25 chickens (med to large sized), where the chickens can't trash the food with junk (dirt, shavings, chicken poo). Thanks for your words of wisdom!
