My chickens keep dying and I’m not sure what’s wrong.

Sorry for all of the losses. It can be a risk to a healthy flock to bring in new birds from other people. I don’t buy from other people because they may not be honest. Since some had mites when you got them, did you treat them with permethrin or Elector PSP? Mites cause anemia and can kill them. Coccidiosis might be possible with grown birds if they move to a new home with different strains of coccidia. By all means if you lose another chicken, keep the body cold, not frozen, and send it to your state vet for a necropsy and testing. Cost varies from state to state. What state are you in? Here is a list of state vet labs to discuss this:

Curious where one would purchase Corid and Elector psp?
