Pale combs and face after lice treatment

[Bailstorm]

Hello poultry lovers! Our hens recently came down with lice/mites and were treated with Y-Tex Garden and Poultry Dust as per the recommended treatment method. They're feathers seem to be coming back really nicely but the skin on the hens with the worst infestation are now turning pale and shriveled. Should I be worried??? I thought possibly frost bite but none of the other hens seem effected.

Welcome to BYC. Stress can be assisted with the use of poultry vitamin-electrolyte-probiotic powder in waterers 3 days a week. If you dusted once, you will need to dust again in 7-10 days for any mite/louse eggs that may hatch. You will need to remove the birds to a temporary location, clean out the coops of all litter and dust treat all walls, ceiling, roosts, floor, nests, cracks, and crevices of the housing. Permectrin II, Atroban 11% EC, Ravap EC, are a few effective spray concentrates which are safe to use on premises as well as the birds so long as label directions are followed. How old are your birds, and have you ever wormed them, or treated with a Coccidiosis preventative?
