Still losing chicks - breastbone exposed? What disease is this?

[southdakota]

I am still losing chicks. At least two a day. I have added TF-15 to their feed, added corid to their water, added albon to their water
They become lethargic, fluff their feathers, and when they die their breast bone is no longer covered with any skin...SOme of them have closed eyes and labored breathing. Any ideas?

I'd save some in a zip-closed bad in the fridge and call my county extension office.

You don't have rats or mice do you?

is the skin streched thin and translucent or is it open? Is there blood?

 

[southdakota]

No blood, no open wounds, it doesnt look like they have any skin on their breastbone, so it must be stretched very thin

I guess pictures would help- what feed are they on?


What arrangement - brooder box with lamp, hen, no heat, heating pad...

I'd look up side effects of all of those medications and check for OD too.

Good Luck
