I have checked couple of chickens and their skin is clean, no blood or wound or anything. But I'll use the fly powder and spray if needed. Thanks everyone for replying.
Last couple of days I'm noticing these tiny bugs are flying all over my chickens. Seems to just flying around them, sitting on them, nothing more! How can i get rid of these? My chickens are free ranging. I am adding some pics if it helps. Pls help! Thanks in advance!
