Earlier this month I found a dead sparrow in my chicken's water bucket under a tree. I assumed it fell out of the nest and couldn't get out of the water. I cleaned out the bucket and went on. Then, a week or so later, I found another dead sparrow in the chicken's bucket of water under the tree. I thought "oh weird!", cleaned out the bucket, and went on. Tonight I found a dead sparrow in the chicken's bucket of water under the tree and another in the coop bucket of water. I'm now thinking something is wrong... Could this be some kind of bird flu? Could this hurt my chickens? Please help! This has never happened in the four years I have had chickens!
