You will need to use this stuff for tape worms... http://www.horse.com/item/zimecterin-gold-praziquantel-paste-wormer-775/SLT151412/
I believe the dosage is .05 ml per pound of chicken. (about a pea sized dolup for the average sized chicken) (Kathy knows more about measuring than I do. :-) @casportpony
Make sure to be meticulous in cleaning around the coop and run, if the tapes are segmenting, there are hundreds of eggs in these segments waiting to be eaten by the chickens. So be as clean as possible for a while to get rid of these things. Tapes are not easy to kill off.
Good luck and keep us posted!
So I've done some research, horse paste comparisons, and a little math (you know me ). The most commonly recommended praziquantel does seems to be 10 mg/kg, so the dose for the two horse paste wormers are:
Equimax has twice as much praziquantel as Zimectrin Gold, so you only need to use half as much.
Equimax - ~0.03 ml per pound
Zimectrin Gold - ~0.06 ml per pound, though 0.05 ml is probably also effective.
Doses for a five pound hen
- Equimax - 0.16 ml
- Zimectrin Gold - 0.3 ml (about a pea size dollop)
Repeat in 10-14 days I think.
