Here is a warning about the small plastic feeders w/an open top. I have the large galvanized feeder and I have had no problems with it. But for scratch treats I use (used) the smaller feeder. Well no more! I came home on Monday, went to let the chickens out of their run and into their yard and what did I see?? The tail of one of my girls sticking out the top of the feeder (which had blown over)! I ran over because it was very very still, I just knew she was dead but thank God she was alive. I tried to pull her back out but as you all know chickens don't do BACK very well, so I pried the bottom of the feeder off and pulled her out. She is fine but her comb and the top of her beak are bruised. If it was going to happen, then I am glad it happened to one of our calmest birds, a Wellie, because one of the more spastic birds would have probably gone shocky and died. It's totally my fault. I thought they were too large to get into the dang thing. When they were smaller I used to stuff a Nerf football in the top to keep them out. I left the feeder, in two pieces, in the chicken run so the little Wellie could go by and kick it if she wants to!!
