Megan , I'm not trying to pick a fight . There is a lot of mis information out there. Ivermectin is not labelled for use in chickens and any avian vet worth their salt would tell you that. You may well eat the eggs and have no adverse effects but someone else may have an allergic reaction to it. Neurological damage is not always obvious straight away. There have been many discussions on ivermectin . We use it on our cows and yes it does have a withholding period, that is why our cows have to be ID and property tags . When it is sold at market if there are any health issues it can be traced back to your property. So the only reason there is no definitive withholding period is because it is not tested on chickens and nobody has the answer.
Lucas, just my opinion, but I would be exercising a 10 - 14 day withholding period, as in poultry specific wormers.
Btw pestine poultry powder does work but you need to treat at 10 day intervals as you would with head lice . Otherwise you are wasting your time and money.
Yeh I know that I just wanted to know why people are so against it when vets recommend it that's all.. That's what I said everyone should so their own research, and I was trusting my vet/ local poultry..
Thankyou for the information anyways
