I believe my roosters have worms. I have found on here that you can give them valbazen, which I already have. However, I do not want to catch almost 100 roosters we were planning on slaughtering Saturday and orally give them valbazen. There must be another way but I could not find it. I have the liquid valbazen and says "Alendazole....11.36%". Can I put this in the water? Also, there is a withdrawl time for our goats but what about the chickens? As I said we planned on moving them to the freezer Sat. How long should I wait? The stool is slightly bloody on some with worms. I have dealt with cocci and I am sure this is not it. Besides, all the chickens were treated.
