OK, I did a BIIIIGGGG no no!! I got a new pullet from the same breeder and "assumed" that all would be ok and I can just add my new sebrite in at night with my 4 other girls (all have the same hatch date and were in the same brooder at the time I picked out the original 4) Houdini (new bird) has been here for a few days and I wanted to give her a once over and saw a wheat-colored bug cross her skin when I lifter her upper wing feather (the mite was on the TOP of her wing, not her armpit). I continued to look her over and saw one more. Nothing like a major infestation like you see with the red or black crusty skin but it was very obvious to me our new gal has a few mites. I dusted all five with food grade DE. Do I need Sevin dust now or some other pesticide? I looked over the other 4 and not one mite was found...I was a little rude about flipping them over and under and really checking the vent I even got the itchies myself just because I saw a mite... I am a newbie and this is my first mite sighting. My crew is 3 months old. Now, if it were dogs and we were talking fleas, ticks or ear infections...I'd be more than prepared! So what is my next step? And was I wrong for dusting with the DE?
