I checked over a chick that was looking a bit unhappy today and she was TEEMING with bugs. I rushed and gave ger a bath in Poultry Protector, blew her dry and dusted her with Sevin. Then I checked over the other chicks and none. I looked closely and really searched several spots and the others may have one or two, but not like the other one.. What's the deal with that? I have also noticed some of my chickens are the same way. One will have visible fleas/ whhatever and others....nothing.
