Pour On will treat lice/mites but it's not that effective in treating intestinal parasites - it may still treat Roundworms. It is still dosed and administered by weight!Thanks you for the dose amounts, very very helpful and I will make a note for future reference.
I also just picked up Eprinex Ivomec Pour-On. I thought it would be easier going forward to administer vs. orally administering to each bird.
Most all anthelmintic doses are based on weight - each is different. It's not hard to give each bird their oral dose when giving Safeguard or Valbezen. I draw up doses and have them ready. Go out early when chickens are roosting. Grab a hen off the roost, give her the meds, then set her down. Go to the next and so on.
The only difference between Pour On is you would apply the liquid to the base of the neck along the spine - it must come into contact with the skin. It's repeated in 10 days.
Treat your hen's crop issue. See if she improves.
