Recently at my local supply store i was advised that i could make and use a spot treatment out of permethrin 10% for my chickens to deal with the lice infestation..... I did as was told, and it did clear up the lice within 3 days, and i noticed that my rescue hen had her first "normal" poop..??? Since then i have looked through every scrap of internet info i could find and found NO information on using this product this way. (That's why i omitted the dosage) I think it may have worked on my hen's worms, but will not know unless i can get a fecal. Everybody is clean and happy, and no complications were observed. Details: Easter Eggers, 1 roo and 2 hens, 1 orpington hen, 1 bantom cochin. Body lice observed on butt and under wings. Possible mite infestation previously, as there were pale combs and missing feathers under wings and on "drumsticks", and tired during day. Feeding 1 Tb manna pro showbird supplement/bird/day + scratch. Frothy runny poops occasionally, with skinny worms, poops occasionally full with definate roundworms (After a day of pumkin eating :O) one poo i thought looked perfect, then i noticed what looked like a piece of rice coming out (Horror) Then recently found what looked like a tapeworm segment. Previous treatment was DE and pumkin guts, and the manna pro poultry protector-Would NOT recommend; used up after 1 and a half birds and still no dead bugs. DE worked short term, but they kept coming back. Treatment so far: 1x @ beginning of a month, again at end when saw bugs again. Saw tapeworm segment and followed up again at 2 weeks to try to kill. Everyone is eating and drinking good, no bugs, no worms in poop; poop is perfect green with white cap. Only thing wrong is CRD (foamy eyes, phlem) I would desperatly like information, good or bad! I probably should not have done this, but was out of options. The other stuff was out of my price range and these are pets. I knew the risks, but took them as an alternative to the lead one, and now am wondering if there could be internal damage??? I got these problems by buying from the local auction and not being aware of symptoms until already too late.
