Hello, good morning, I live in central Oregon, the high desert. My flock is happy, waiting for warmer days, just like the rest of us Today I was noticing that there are quite a bit of little birds (8?) hanging around in the trees that grow in the chicken run. They even scoop down and sometimes walk around close to the chickens; nobody seems to mind. The question is: should i be worried about those wild little spring birds bringing disease to our flock? Do i reallly need to put a roof over the run? The hens sleep inside a safe coop inside the run, so predators are for the most part not an issue, but I'm not sure about letting the girls mingle with the 'wild side' Peeeeace, 'B.
