My question is how would the chicks have access to coccidia in a brooder with fresh bedding. They have to be in contact with soil to consume any oocysts. It doesn't come from the air. So, IMHO, especially since you're in a desert environment, I doubt it is coccidiosis so I wouldn't treat.
Sudden death in chicks that age range from sudden death syndrome (common) to pullorum, infectious anemia, necrotic dermatitis and necrotic enteritis. I doubt it is any of those since they're rare. Sometimes chicks just fail to thrive. SDS cause is unknown.
Thanks, I shipped the first chick I found off to be necropsied. I hope to hear from them in a few days. I"m not sure how fast the turnaround is for UC Davis.
I have always hatched small batches of chicks at a time, never this many. Is there a possibility these were trampled birds? Are small chicks able to trample others?
Turns out to be the second chick to die was one of the older chicks (a week older than the others), That was the one I found Friday. The one we found in the bedding couldn't have been dead for more than 6 days, since I emptied out and cleaned the brooder last weekend.
If 1 chick died for a NON contagious reason, and we didn't find it. Could the decaying body get anyone else sick?
