I'm sorry for your loss.
I recommend that get a necropsy through your state lab to confirm that Coccidiosis was the cause of their decline.
An established adult bird should have quite a bit of resistance to the Coccidia found in their environment unless an underlying condition or other factors come into play.
For you to lose 2, that's a great concern.
You can find your State Lab Here. Wrap the bodies in plastic and keep them cool/refrigerated until you can get them tested.
