went to feed my flock and found 1 of my 4 week olds dead with red specks look like wood mites . have a lice and mite problem all of a sudden. have 3 four week olds in a seperate boxed off corner in coop. and another set of 3 , 3week olds. and a broody with her 6, 2 week olds. all seperated in there own corner. my older flock seems to have lice and now looks like the chicks have it. i treated coop saturday for mites sprayed the coop down with bleach water. also used insect killer spray on all the walls and roosts nestboxes. i sprayed all the 1 yr old birds with poultry protector. found out its a protector from lice and mites after i treat with a poultry dust . so i got to find a dust to really cure the lice and mites problem.
