I have searched high and low and I still feel a bit confused. To start off, I have 70+ chickens and only free time on the weekends. Everyone seems to reccommend 10 days between worming treatments.(wazine in water and ivermec pour-on?) however, I only have the weekends where i have time to worm chickens. Even removing water in evening and putting in treated water the next day would have to be a weekend job. Do I do a 7 day wait in between wormings or 14 days? Also, is it possible to be safe and effective to instead do one dose of ivermec pour-on? I havent seen actual worms, but because of their unthrifyness I suspect it. I was hoping that I could do one dose and not be too risky on protien poisoning from dead worms.
