We are considering getting a bird feeder for wild birds over the winter. Our chickens are free range so how likely is it that this will effect them? We would put it on a high post BUT it will have to be screen bottomed so it can clean out the manure when it rains and not let it sit. It is not in one of their favorite areas but they forage everywhere. They will not be allowed to forage on exceptionally cold days but if it is above freezing chances are we will let them out. How many of you have bird feeders for wild birds? Have you had any problems? How can you tell if wild birds are sick? Thanx!
