Thank you. Can my infected birds stay with the others after the first day or so of medication without infecting them?No, the tapeworm eggs must be eaten by an insect. The infected insect then must be eaten by a chicken in order for the chicken to become tapeworm infected. It's called the "Indirect lifecycle" of tapeworms.
Chickens are more susceptible to roundworm infections since the roundworm eggs can be picked up off the soil and eaten/swallowed, which starts their lifecycle. This is called the "Direct lifecycle."
Chickens are always pecking the soil. They pick up the eggs and are swallowed, starting the roundworms lifecycle.
Dont confuse the roundworms lifecycle with the tapeworms lifecycle.
Once Praziquantel is given to a tapeworm infected chicken, the tapeworm will be excreted within 3 hours. Depending on the size of the tapeworm; you might see jellyfish looking strands excreted, broken up flat pieces of tapeworm excreted in pieces. You may not see anything due to a small sized tapeworm.
Benzimidazoles are effective against all types of poultry roundworms.
Roundworms may be excreted in feces a few hours or sooner after dosing with a Benzimidazole. They will be dead or dying, they cannot survive outside their host. Benzimidazoles are effective for 3 days after dosing.
It always best to reworm chickens 10-14 days after the first dosing to kill worms hatched from eggs.
