I found a single roundworm in the chicken poo two weeks ago. I treated with Wazine. I understand I should follow up with Ivermectin. Our store only had a big bottle of Ivermectin pour on that was like $75. No thanks. So I got one of the tubes of horse paste. I've searched and read a bit but am still a bit confused. They chickens are 9 months old and this is our first time worming. Questions: How much paste should I used for each bird? I have Brahma and EE. All large fowl. One roo who is bigger than the girls. Do I put it on top of the beak and kind of smear it in? Or inside their beak so they eat it? How long until we can eat the eggs? I've been treating my roo for a mild but persistent case of scaley leg mites. Will the Ivermectin kill those? Thanks!
