I have decided to worm the chickens since i am noticing some thin-looking breasts in a lot of them. I just found my bottle of piperazine and looked it up but found a lot of mixed results. what's the dosage in the water & what's the process? is this the only way to get it into them? how long do i have to toss the eggs after treatment? Chickens are (2) 2mo old mixes, (7)3mo. old standards & some mature bantams, mostly cochins. Also, should i worm the ducks too? if so, how would i go about doing that? they all look fine, fat & healthy, except for a few newer hens... but im not sure if i should worm anyway. thanks everyone!
