I was doing a lot of weeding yesterday in my garden, and pulling up a lot of nice edible things -- dandelions, chickweed, dock, garlic mustard. Which I always give to the birds. I had to be careful not to give any clinging soil to the turkeys, since earthworms are the vector for the parasite that causes blackhead. Just got me to wondering -- wild turkeys no doubt would feast on earthworms, especially during those warm spring rains when the worms come out and carpet the ground in the morning. So, do wild turkey populations get blackhead? Or are they somehow immune to it?
