Hello! I have 6 chickens and most have tapeworm. I bought Mediworm powder and I'm not sure about the dosage and how to administer it. The directions say to make a suspension of 5 g of powder to 20 ml of water, then dose 2 ml of the suspension per 100 g bodyweight on a empty crop... Has anyone used this and if so, can you give me easier directions? This is the first time I've raised chickens.
