Do you have your run covered?. The only thing so far in the wild birds that get in mine are the titmice. They don't stand a chance once the girls are let out of a morning into the run. No bird gets in. They would kill them. If yours are free range there is no way that I know of to keep them from eating it. Jean
measure the feed out, just enough that your birds will eat in one "Sitting.." wild birds will bring in mites and all kinds of diseases... plus measuring them out will keep your birds more healthy weight wise.
