I have eight 2-3 year old does on a 2 1/2 acre plot. Six 5-6 month old does on 1 acre and 2 buck on 1 acre. They all have clean water, their feed troughs are up off the ground, there is plenty of grass and browse. It seems like one of the grown does is always getting scours. Every month it seems like one of them is sick with cocci. We usually take a fecal test to vet to be sure and then we end up treating with Corid (per vet). We worm them all with Cydectin and Equimax paste on a regular schedule. I purchased some Valbazen yesterday but we have not used it yet. Any recommendations or suggestions for getting this under control. I hate constantly having to treat with meds but sure don't want to lose any of my herd. The one or two of the baby girls got sick a month or two ago but we attributed that to stress from being weaned from the moms and moving to a different pasture. Any advice would be greatly appreciated.
