hi guys ive finally posted pics of my coop + run set up, it still incomplete... the roof and the door is coming soon. anyhow, i try and poultry powder the chicks about once a month. however, as you can see the grass in the run area is pretty much dead. all it is, is basically dead grass & dirt. when i looked closely on the ground, i noticed so many tiny red coloured MITES! my god, the colonies and colonies crawling around. the white stuff on the ground is white poultry dust. but i dont think these things last very long. i cant dissinfect the floor as the chickens walk around it and peck + roll around on the ground. does anyone have suggestions? im sure every single person in here who has a chicken, run or coop area...will have the same thing. (unless concrete floor that is hosed down daily of course. im a bit too scared to walk into the coop now, in fear of getting them crawling onto my body and brining it into the house YUK!
