I haven't found anywhere that sells pigeon food. I only have a pair. I feed my ducks and chickens gamebird grower, scratch, and whole oats. Could I pick up some split peas and lentils and mix it with what the other birds get and provide a decent diet for them? What percentage protein should I feed them? They are woe tumblers, and aren't flown or breeding. What sort of green food do they like and is it good to give them some veggies once in awhile?
