Help new sheep owner.. brown watery poop

[YourRabbitGirl]

New with sheep! I have had them for three days. Have them on same pellets and corn mix that previous owner was giving them. Have only been giving it to them once a day. This morning my husband went out and noticed watery brown poop in pen area? He also noticed they didn’t finish eating the corn mix from yesterday. Could it be the new grass making them not feel good? I have salt lick I pen also with them. I’m afraid they might not be drinking enough water? Any ideas? All three have been wormed.

Sulfa drugs (sulfadimethoxine sulfamethazine) such as Albon ® and Sulmet ® are most effective in the early stages of acute infections when coccidia is rapidly multiplying. Sulfa drugs can not cure coccidiosis but are often administered to infected goats to avoid secondary infections such as bacterial enteritis.
