how concerned should i be about internal and tiny to microscopic kinds of pests... we have practically every predator you could fear here, and on a regular basis... two separate owl families (barred and horned), countless hawks, at least two bobcats, coyotes, red and brown fox, opossum, raccoon, and i know i must be missing something else (other than suddenly, the new neighbor's dog and cat), theses were all of the things i had to reconcile before we decided to keep chickens, but i'm wondering if i should be more concerned about the variety of constant critters around the coop... (oh, and should moles concern me??) i know i have read about turkey diseases in particular, but thankfully the turkeys usually travel on the other side of the house. however, there is a pine tree right near the coop, and it is almost always enjoyed by whichever birds are in town... should i be concerned about mites, or anything else, this time of year? then there are the deer (the chickens are still getting their fill of ticks i think, as we've tracked several in the house- one of the reasons we thought they would be great to have around! but) i wonder about anything else they might be tracking around... for example, bot fly!!! (ugh, we just killed a mouse recently that had one crawl out!) and of course, mice/rat disease.... i keep the water out in the pen portion of the coop, is this a bad idea? i suppose the smallest of small mice could get in and out from someplace. so many questions, only six chickens!
