Thanks. I finished off the layer feed and was thinking about buying more but I'll stick with just oyster shell. I like those feeders. My chickens make such a mess. They do better with crumbles over pellets but the oyster shell looks they have food fights with. They flick it onto the floor then scratch at it till it goes flying. Silly birds.I would continue with free choice oyster shells. I use rabbit feeder type hoppers in each pen, one with grit, the other with oyster shells if pen contains laying hens. Does not take much room, and just keep an eye on them, add some shell and granite maybe every couple weeks. Just ran out and took a pretty bad phone shot, but you can get an idea what I mean. Not much waste with these.![]()
