Ryan excellent advice, I agree with you.
I would not treat your fawns any differently yet Jeremy. As long as it's not watery, they are ok, just get dirt like Ryan suggested if you don't have any, mine eat a lot of dirt, especially when they are real young.
If you do start seeing full blown scours I will let you know what has worked for me. When I notice scours, I will give some fawn paste right away. Then I will let that digest in them for a few hours. Next feeding I take less than one ounce of their milk, pour it in the bottle and fill the rest with water ( you can add electrolytes to the water if you prefer). The milk is just flavoring to get them to drink the water. We humans would never drink milk when we have diarrhea so why should the fawns? Now I relize the fawns aren't getting many nutrients, but they will be ok for a day. The trick to this is to do it strictly for 24 hours, even if the fawns begins normal bowel movements before then, don't give more than an ounce of milk, do mostly water. The next day, start sneaking the milk back in. Start with maybe ounce and a half, then by days end maybe 3 mixed with 2 ounces water (going by your 5 ounce per feeding) if the diarrhea comes back, you probably put to much milk in so back it off a little. It also don't hurt to give pepto bismol between feedings. I have had great success with this treatment, no meds other than probiotics and pepto. It usually clears them up in 24 hours or less. I got the basic Idea from a forum member years ago, but I cannot remember who it was. I tweaked his or her instructions a bit to fit my liking over the years.
