Hi. Now have four 3 month old chicks that are thin. I raised them indoors and they were fat and healthy at 2 months when I put them in outdoor coop and enclosed run (run is raised above ground with pea gravel as base) We had two straight weeks of cold rain. At 2.5 months noticed coop crawling with red mites but no infestation on Hens. No sign of lice either. So deep cleansed the coop and run and sprayed permithian everywhere! Gave the girls a bath with dawn soap to smother bugs then a rinse with apple cider vinegar water to clean the skin and get a closer look. Did not see an infestation but blow dried the girls to get them warm and happy. (So figured night sucking mites that leave no trace. Girls were thin and looked anemic. Combs pale in comparison to sister hens at neighbor house.) sprayed permithian again two weeks later. Fed probiotics, spinach, and garlic and eggs to get iron back up. Added DE to sand for bathing and all over coop. Then noticed foamy poop so treated five days with Corid 2 tsp per gallon suspecting cocci due to the moist environment in the run (girls not allowed to graze outside much due to construction in yard). After Corid treatment, gave some chicken vitamins with iron for two days. I am starting to see some color in their comb, but they still feel thin. Today the youngest one pooped this funky poop. Have I been wrong this whole time? Is this worms?
