I LOVE that feeder. I wonder where I can get one? Will be googling that for sure. I don't really want to take away the food for a day because we have been having a cold snap (night before last was -27) and they really need to eat well. The pasture is currently under snow, so not much to be gleaned there. LOVE the feeder though.
I forgot you said you had snow on the ground. I was just trying to throw out suggestions.
Hopefully the treadle feeder will work for you and prevent the starlings from eating the chicken feed.
