I have 13 young chickens, 10 - 3 week olds, 1 - 8 week old, and 2 - 6 week olds. I was told they were all vaccinated for coccidiosis at the time of purchasing but I just brought home the 2 - 6 week olds yesterday and because I was told they were vaccinated for Marek's and coccidiosis I didn't quarantine which I am now extremely regretting as the seller I purchased the two new ones advised me today they actually weren't vaccinated for coccidiosis and then this evening I noticed blood tinged stool from one of the chickens but I am unsure who it came from. I know all the other birds were vaccinated but now I am unsure what to do as I keep reading you don't want to cancel out the vaccines by giving the whole flock treatment but then other articles say if one bird has it the whole flock is most likely infected... I'm at a loss and I'm not sure what to do I don't want to lose anyone especially since I have just started. Thank you for any advice! I will be bringing in a sample to our vet tomorrow.
