    Having discovered lice on a few of my chickens yesterday, I purchased Eprinex today. My question is regarding the dosing for different sizes and ages. I have BO's, bantam brahmas, juvenile wyandottes that are nearly 3 months, oh, and a couple broody hens that have been setting on eggs since approx. April 30th. I also have on hand, Sevin dust & liquid concentrate, another garden/poultry dust I got at TSC and an organic concentrate insect killer that says it's safe for use around the home & pets. Thought that might be useful in the coop and nest boxes. And ifo or tips would be greatly appreciated. [​IMG] Headed out now to move my broody girls and begin the clean out...

    Quote:Keep in mind that eprinex is a wormer, anything else is secondary. The dosage for worming and lice/mite treatment is universal. For standard size chickens dosage is 1/2cc... smaller chickens it's 1/4cc. I do not recommend dosing chicks with a wormer less than 18 weeks old due to their innards and organs not being fully developed and not coping with the wormer. It would be best to lightly use sevin dust on chicks if you actually see lice on them. You will need to dust their house, roosts and nests and repeat in 10 days, same with chicks/chickens.
    ETA; The eprinex is administered on bare skin on the back of the neck, use a syringe without a needle.

    Thanks so much Dawg. Just what I needed to know. Now... where DID I put that syringe...? [​IMG]

    Quote:I have used Eprinex pour on before. It is super thick and I used about 10 syringes to treat a flock of about 90. It breaks the syringe because it is so thick. You might want to have extras on hand.

    If the Eprinex doesn't end up working for you, the lice you have might not be sucking and biting lice. There are lice that just eat the feathers:

    I agree with everything dawg53 said (but I didn't know about the 18 weeks old thing- thanks dawg53).

    I would never use sevin liquid on a chicken, although I don't think you said you were intending to.

    My DH made me toss the eggs for three weeks, although everyone says there is no egg withdrawal period for Eprinex (on cattle). This is used off label- intended for cattle.

    You have to use your judgement and decide how long you want to toss eggs or not at all.

    Yeah, was debating about the eggs. They told me at the farm supply that I wouldn't have to hold off on the eggs, but I might just for the heck of it. LOL! We can't usually eat all we get anyways. And since my boyfriend is working 7 days a week, 12+ hours a day right now, guess it's just me on the clean & treat detail. And, whew, it's hot out there right now! [​IMG]

    Some folks scramble the eggs and give them to their chickens when they want to toss eggs, although others argue that you are giving the medication to them again.

    Hey, that's a great idea. Like it better than throwing 'em out. Thanks. [​IMG]

    It would extend the withdrawal period because of wormer residue in the eggs...that's why there's a withdrawal period. Keep in mind that wormers are poisons.
