I recently (four days ago) purchased seven baby chicks from a breeder that I know well...she takes very good care of her stock...three of the chicks had colds and she gave them to us, telling us how to care for them (if we wanted to try to nurse them back to health)...I have kept those three separate from the others. Two of the others are a pair of barred frizzles and then the last two are a pair of cochins...those four are in my garage under lights. The four in the garage (both pr in sep containers) have been acting fine, with no s/s any illness. This morning I went out to check on them and one of the frizzles was pooing what looks to be blood...I have pine shaving in the container, and on those, it looked a bit pink...I think it is b/c it was leaching off onto the wood and making the color appear less bright...SOOO, this leads me to my question...how do I know if it's Cocci or intestinal lining? I've seen the pics on here, mine looks similar to the lining ones, but a bit darker...all formed though as best I could tell. By that, I mean that there were no "pools" of blood...I cleaned the container our and put new shaving last night, so Im sure it just started this am. They have been on medicated chick starter and water with duramycin (at breeders rec d/t the ones being sick and them being transported here together) I have been mixing the duramycin at 1tsp/gal. I know the antibiotic wont treat the cocci. I have read a few posts on there about vinegar and yogurt...if anyone has any info about this tx, pls help me be more informed...other question...corid or sulmet? I found corid at a feed store close...dont know how to mix it though as they said it is generally used for cows. Am I supposed to by it specifically for chickens or use the cow one? HELP!! Also, do I treat my entire flock? I have 19 total...the seven chicks, eight grown birds, and four young silkies. All the chicks have been separated from the other birds the entire time. Thanks for any help...these are our pets and I am so hoping we can save them all...any tips for the ones with colds would be appreciated too...one has "sick" eyes (breeder treated before we left, but they are still matted and weeping)...they are all getting better though.
