I am looking for a dewormer for my chickens and cannot find anything online! My chickens have roundworm (I saw it while cleaning their droppings). Please let me know if you have a link to a website where I can buy a dewormer. I have looked for Safeguard Aquasol and Flubenvet 1 % Medicated Premixture but couldn't find anywhere to buy it. I appreciate any help with this!! Need to purchase dewormer fast! Thanks!
