The rod spins to keep chickens from scratching in the feed, sitting on top of it and pooping in the feed.I do. There is a metal rod like thing that sets in the middle of the feeder, it came with it on, and I seen her do it and the RIR or New Hampshire Red (not sure which she is) has it has well. But the other girls don’t have it. I’m wondering if when that metal gets hot, it’s causing it to almost like burn it. I did take it off today, went right out of the coop. I honestly don’t even know what the purpose of it is.
Those feeder troughs are made of galvanized metal to prevent rust, which contains zinc, lead and cadmium --- and I wonder if THAT might be causing the black spots on his comb??? I'm reminded of warnings I've read to wash your hands with soap and water after handling galvanized metal - due to the risk of skin reactions. Some people are allergic to it. (Chickens too?)
Galvanized metal, at normal temperatures (below 392-deg-F), is safe for contact with non-acidic food and water. And it occurs to me that MANY of us use ACV (apple cider vinegar) in their birds' drinking water. And touching all that hardware cloth covering our runs! NEW hardware cloth should be washed in vinegar, rinsed, and coated in linseed oil before exposure to birds. Really???
Uh oh.
