We bury ours, deep. Do your chickens have access to the compost pile? If they do, and the poults are the only ones dying, it's probably blackhead.

No actually, the chickens are all in pens, just the Turkeys roam unless a chicken gets out, but they don't regularly head there, the Turkeys scratch through there once a day.
Do you bury everything in the same place?
The people before us didn't have chickens here for at least the last 8 years.
We dig a new grave for ours.
