In my suburban backyard, we have many squirrels, 45 varieties of wild birds, and the occasional opossum and raccoon. My chickens (3 ladies) have the run of the yard, and are cooped at night. I just noticed a squirrel that appears to have distemper or something like that. It weaves from side to side, acts drunk, tail droops, etc. It is very hungry, and was eating from one of the chicken's feeders and drinking from a waterer. Can it pass a disease to the hens by sharing/contaminating their food and water supplies?
