We've always used Equimax because it covered all worms...but then I got to reading about the worms getting resistent to it, which I guess would explain why the girls now have bot eggs on their legs.
One of the mares is 9 and the other is 24, they are only pastured with eachother in a dry lot and get hay morning and night that usually lasts them through until their next feeding. They are fed Blueseal Trotter. Its getting colder now (I think that matters? LOL not sure) but no snow yet.
Anything else you'd need to know, just ask. Thanks to anyone that can help
