Excellent thoughts for half coffee capacity
I have shoes I wear only in my backyard and typically don’t let anyone out with my flock for the reasons you’ve mentioned. When I moved here we also had a new neighbor move in across the street. Come to find out he was dumping literally pounds of pigeon feed in his yard every day for the wild pigeons. I had a huge problem with them coming into my yard to eat chicken feed and once the people moved away it was even worse. There were easily 20 pigeons that died in my yard last summer alone. Eventually they were unable to fly so if I could catch them I’d throw them over the wall to the front yard and hope one of the neighborhood cats would get them. Otherwise they eventually couldn’t walk either. I called to see if I could get a necropsy on one of them but covid prevented it so I ended up putting down my entire flock of chickens. The only other place I ever got actual birds from was someone here and she doesn’t have issues in her flock. Otherwise I hatched my own eggs or eggs from people I trust. The difference is that her chickens are kept in a run, mine aren’t.
I am outside well before sunrise on a regular basis and I’m hearing a lot more roosters around the neighborhood, so there are quite a few people around here keeping chickens. If wild birds visit them, then come here they can spread disease. Rodents as well. Shoot even the wind can carry Marek’s in the dust and dander. This is why I really wanted to try out the EFs. They are supposed to be heat hardy and have disease resistance to Marek’s among other things.
