I have learned a lot about cryptosoridium today from reading about it due to your necropsy report. It is a parasite in the soil similar to coccidia, and can infect the respiratory system in chickens. They also mention mycoplasma, which is CRD or MG, and is a respiratory disease. So those are two things that are infectious, and probably have spread around your flock. Kathy may know a lot more about crypto than I do. The enteritis was probably the real kicker. If you do decide to depopulate, I would cull every bird and bury carcasses deep or incinerate them. After cleaning and disinfecting equipment, I would wait several months before getting new birds. Any birds I would get would come from a hatchery all at the same time, so that hopefully not get any any carrier diseases. I would also do a preventative coccidiosis treatment on those chicks once they get on soil, and continue it for a bit afterward, or treat them periodically at the low dose every 3 weeks. Sorry about your birds. Here are some links in crypto and MG:

After re-reading your first post, it looks like he had E.coli in his lungs which is usually a secondary infection of MG or CRD. I am an amateur, so I am doing the best that I can to decipher the reports. A vet on here may do a better job.
