I have a 4 month old who has been sick with worms, I believe, so I gave him Piperazine-17 in his water 2 days ago. I saw him drink at least a few big swallows. There have been worms shedding in his poop (just a few). He doesn't poop much because he isn't eating much despite me making lots of food available (regular feed, yogurt, scrambled eggs, yogurt, buckwheat (cooked), sunflower seeds, applesauce, bits of hamburger. He only makes a few halfhearted pecks at the food once in a while and just sleeps the rest of the time. I thought he'd be better in a few days. But he doesn't look better -- he just sleeps all the time and refuses food mostly. I thought the worming would cure him, but he's still listless. And very thin. Can I dose him again with the Piperazine -- how much does one chicken need to be cured (the directions said mix 1 fluid ounce with 1 gallon of water, which I did. Then to feed that to 50 birds until it's gone). Well, I just poured him some in his water dish. Or am I just torturing him?
