I have a flock of nearly 30 and for the past couple of months they've had worms. About a month ago I got some piperazine dihydrochloride 53% and gave the recommended dosage in their water, but just today I found a wormy poop. I gave them another dosage and a half this time in their water............ what other ways can you get rid of worms? a few of my girls are significantly lighter than the others, and have been getting about 15 eggs a day, when I should be getting at least 20 (i have 4 roos..) my birds have also had an ongoing battle with lice, how can I get the lice gone? I can tell they are really bugging one of my hens, and im worried that the chicks will get an overload of them too.... I have a big bag of DE, should I put that in the places they like to dustbathe?
