    It is always best to have a vet check fresh poop to determine if you have too many worms in your flock.
    Most vets, who do not see chickens, will still test poop if you bring it in.
    (It's very easy to pick up a phone and call around to ask.)

    Most all state vets will allow you to over night fresh poop to them for testing.

    The most common worms are roundworm and cecal worms.

    Treatment for these two are ONE dose of the below medicine (choose one) on day one and then repeat one dose in 10 to 14 days. I would recommend throwing eggs away for 2 weeks after second dose.

    1. Albendazole (name brand Valbazen) .08 ml per pound

    2. Febendazole (Safe-Guard and Panacur) .23 ml per pound

    3. Febendazole (Safe-Guard AQUASOL) (Only product with NO egg withdrawal time)

    4. Praziquantel (Equimax) .03ml per pound

    * I do not recommend adding any of these to their waterer or food (except AquaSol). It is best to dose each bird straight to the beak to ensure they get the correct amount.

    **It is best to weigh each bird to get the proper dose.

    Does anyone use pyrantel pamoate? I have a huge bottle of this!

    Would all these be considered safe for the selling of eggs. I know AquaSol would but at $250 I can’t afford that.

      These are all used off label. IMO you should NOT sell or eat eggs for at least two weeks after using a wormer.
      Except for AquaSol.

    OK this week I will be using the Safeguard on my 5 hens...Should I throw the eggs away after the first dose also?

      Yes, I believe that is safest.

    Only throw eggs after the second dose?
    Is there such a thing as a "maintenance" worming method? Just curious....thanks.

      I would throw eggs away starting on day one of treatment all the way til two weeks after the last treatment.

      The following medicine has recently been approved for laying hens with NO egg withdrawal:
      Aquasol. You can read about it here in the very last link listed above "FDA Approves..."

      Can't you feed the eggs to the chickens, until after second dose has run it's course?
