The only threads I could find were re: adult chickens, so forgive me if this is a duplicate post. Monday, I picked up some 6-7 week old chicks. A friend of mine and I bought some from the same person. My friend picked them all up Sunday night and I picked mine up from his house on Monday. I've been petsitting all week so have had them at that location rather than at my house, in a large plastic storage container in the spare room. I have been doing a complete litter change (pine shavings) every evening, and giving them fresh water and food (Manna Pro medicated chick feed) twice a day. They've not been exposed to any other birds or areas where other birds have been, since leaving the person we got them from's hands on Sunday. Last night, when I did their litter change around 10:00pm, I was putting them back in the container and noticed two bloody stools. Both were mostly liquid, with hardly any solid matter in them at all. I did not notice any blood near the vents of any of the chicks, so I couldn't tell from who they came. All the chicks were acting normally - none appeared sick - but this morning at 6:30am, two chicks were dead. Everything I can find online points to coccidiosis, with the bloody stools, but my friend's chicks are all still alive, and my remaining 6 still appear normal. I'm unsure what to do. It will be too late to do a necropsy by the time I get off work tonight, and I'm sure the bloody stools from last night are useless now. From what I've read, it takes approximately 5-7 days for them to show the symptoms of coccidiosis, which means that they had it when I got them, correct? I don't know whether to contact the person I purchased them from or what, if I were to lose any more (he did give me two free chicks, so at this point I haven't lost any money on them). Is there something I can do to treat the ones that are left, just in case they are infected? I really don't want to lose any of them. Are bloody stools a sign of anything else??
