I've just seen some new behavior in my small flock. They watch for the bluejay to come to the bird feeder. When he does, they come flying from every corner of the yard to stand underneath the feeder. They bluejay kicks down whatever he won't eat in search of black sunflower seeds, his personal favorite. The chickens gobble down everything he drops, and in gratitude, they keep the squirrels away so the bluejay can eat in peace. It seems the chickens are as happy to see the bluejay as they are to see me with the scratch bag. Anyone else have a story about wild birds and chickens living in a mutually beneficial way?
