Here in New England, we have been pummeled with a TON of snow this winter. While my coop is holding up quite nicely, I noticed our run roof started to cave under the weight of ice and snow. I cleaned it off and reenforced it, but yesterday I noticed at least a dozen black birds (and one lonely blue jay) were flying around in the run, while my chickens hid in the coop! It was like a giant bird cage! I opened the run door and shoo-ed all the birds out, and found a small hole in the wire where they must have flown in. I patched it, cleaned the run, and let the chickens back out. This morning, I saw one lonely black bird in there, and when I looked inside the actual coop, I saw several birds perched on the roost along side the chickens next the light! I can't find any new holes in the run walls, and I'm thinking they must have hidden in there from yesterday? Whatever the case, I need to keep these birds away...I've heard that birds can bring a lot of disease into a coop. Any suggestions on how to get the existing birds, huddled around the light, out of the coop, and is there anything I can put outside of the coop to scare them away until i can figure out how they are getting in there in the first place? Thanks for any help you have to offer. Once the weather clears, I am going to search that run from top to bottom to ensure that this never happens again!
