I am new to worming and I have a couple questions before I start to use it so I don't harm the birds. I am going to use Ivermectin by putting it in the water. My first question is how old do you start to worm the chicks and do you still give them 3cc per gallon of water? Second: What times of year do you worm the adult birds, I know before laying season. Third: How many times/days do you give them the wormer each time? And lastly How do you know they are getting enough of the wormer when drinking it? Thanks and Sorry for all the questions.
