This year I have a lot more perching birds around my flock. Partly due to new barn although very good growing season for cover crop is providing lots of habitat. Many of the birds are in poor health and I am starting to find dead ones. Dead and dying birds are in good weight. I am very leary of this development. We are approaching time where migratory birds and something that looks a lot like Mareks Disease pops up. This may be a bad year for such.
