I have permethrin. When you say permethrin coop spray, is that a chicken safe product or can I just use ordinary permethrin concentrate in my sprayer with water?Lice can be species specific, so you probably wouldn't catch lice, but they are bigger, so you might see them. My guess is mites. You rarely see mites unless there's a huge infestation or you've got a bird that's not dust bathing - like a broody hen or weaker chicken. Either way, it's the same treatment. Although I do not see mites, I suspected it here.
For my birds, it started with poopy butt. (It's an orp thing.) As we washed each chicken, I noticed some had red skin and a couple had ratty-looking tummy feathers. Rooster feather damage is usually the head, back & sides of the hens. I know a couple people who are currently battling mites, so I suspect the weather this year may be the reason for the increase.
While my chickens were out in the yard on Saturday, I removed all the old bedding, feathers, spider webs, etc, then did a deep scrubbing, permethrin coop spray and DE after things dried before adding the new bedding. I also did lots of chicken baths and dusted them when dry.
TIPS:
* During/after the bath when the hen is wet, it's easier to inspect skin and feather shafts for mite damage.
* Chicken baths on a hot day help cool off chickens. Also allows you to keep chickens outside and prevents the need to blow dry.
* Easier to dust chickens at night and with a partner.
