Urgent! Very odd poop w/ blood
If there is blood in the poop it could be coccidiosis. I would get them some Corid. 2 tsp of the liquid per gallon of water. If using the powder 1 1/2 tsp per gallon of water. Give this to them for five days. I hope this helps them.
Also I saw your other post. I've never seen poop look like that. Make sure you give them grit in their food to that helps with the digestion.
