Hi, I have 1 pullet from 3-08, 2 from 5-08 and 7 chicks from 9-08. The new ones came with brown runny stinking poop and I eventually wondered if that could have been coccidiosis or could it be stress poo but read someone's site that said they used 1 TBS vinegar to a quart of water and this could bring about a cure. I did this with the 7 chicks and things improved to white with gray poo for the most part but still an occasional brown-runny-stinky. It seemed everybody had the nice poo for a while and everybody would occasionally have the bad poo again. Of course they are on medicated chick starter also. So my question is this; do I need to buy the medication for the water if I am unsure if it is coccidiosis, for like an insurance, is there other things I should be purchasing since I have increased my numbers from small and healthy to 10 and questionable health? Should I buy duster stuff for if there is lice or would I be able to see lice? Ultimately the question is do I do the medications as a matter of course and do it regardless like a safeguard or should I only ever medicate if I have a definate sick bird? (like they do wormings on horses no matter what every 6 or 8 weeks) Also is Sevin Dust anything to consider using or would that be wrong? Everybody in the flock eats like pigs, have pretty feathers and free range in my entire yard all day as they were really doing a number on the grass in their pen.
