So I figure I should probably de-worm my flock of 8 hens, they are just over 1 yr in age. They have never been de-wormed before & they have never shown signs of having worms either, but this is more as a preventative move than a necessary move as I want to keep them healthy. Anyways, I went to the grain store today to get some Wazine & pour on Ivermectin as I have seen that this is what has been reccomended by others on BYC. They didn't have the Ivermectin pour on but they did have Ivermectin paste(which I didn't buy) but I did buy the Wazine. The guy who works @ the store told me I can never use the eggs again if I use the Wazine!!! Well that just doesn't make sense! So I bought it anyways & now I need to know the dose to give them.....I'm figuring 1oz/gallon of water. Do I just give it for 1 day or till they drink the whole gallon??? Then I repeat it again in 10 days, right??? Should I try the Ivermectin paste instead of the pour on?? & toss the eggs after giving the Wazine, for 2 weeks after? So confusing!!
