Okay, That might be one of those, don't tempt fate questions, but after reading Pudget Sounds fly control thread (which was very interesting and informative - Thanks!) I'm wondering why am I so lucky? I'm chicky sitting, so while I'm trying to be the prefect sitter, face it, I seriously doubt I'm any more factidous about keeping things clean than all of you, so why am I blessed? Is it temperature? The pen and the run is in a heavily wooded area, so it stays about ten to fifteen degrees cooler than most of the rest of the city. Is it the bark chips? I laid bark chips (don't know what kind, it was just a big pile she had laying around,) all over the run and pen area to combat the mud and the girls love scratching through it. Elevation? We're not that high up, only 500 feet. Moisture? You know Oregon is damp, but so is Pudget Sound. Is it the age of the pen? I don't know how long she's had chickens, but I think less than a year. The size of the run? The 14 girls are in an enclosure that is about 20' x40'. Lack of other livestock? No one else in the neighbor hood has livestock. The native bird population? The woods are full of all kinds of birds. I know we have bats in the area, but they only come out at night and I thought flies were day time pests. Wind factor? It isn't all that windy, but there is usually a pleasant breeze. After reading that thread, it's like one of those mini miracles that I don't have this problem. I mean, the first week, all I did was clean out all the trash this gal had piled up in the chicken run ("toys" for the chickens, according to her email.) So, with all the garbage (rotting food included) that had been in the run, why aren't I plagued? What am I doing right? Because whatever it is, I want to keep doing it!
