I get a sulfa bolus from the vet to treat the scours as soon as they start drooping. It really helps. I've also gotten really good at tubing them with electrolytes if they won't take it from a bottle. Keeping them hydrated is key. Don't feed electrolytes with milk. Wait an hour or 2 after you give electrolytes to feed milk. Keep them warm and dry and try to keep the sick ones away from the others if possible.
I was able to bring one back from near death with this drench. I used a syringe w/o needle. 3 to 4 times a day per dose. Put water in syringe to give him water. He did not wat or drink nothing for 3 days only wat I would force with syringe. Stand him up as many times u can through out the day. On 3Rd night he was officially down. 1 rst thing next morning. He looked at me. I stood him up. HE WALKED 10 FEET! yes! Right now we call him lazarus. Alive and running. I forgot I gave him la200 3 days in a row.
