I guess the wild song birds bring the lice to the flock if you never bring out side stock in.
Some of the cardinals around here have head mites in the summer.
They loose all the feathers on their heads.
Is this a problem with barn yard poultry?
Do I need to quit feeding song birds during the summer, since the chickens are under the feeders, getting what the song birds knock out?
I wish I had the answer. All I know is there was a young Cardinal I would see in my lot looking for scratch I threw out for the chickens. Since I do not feed wild birds and still had one in my pen I would guess it may cut down on the contact with them if you didn't feed them but it would not stop it.
