Poor Snake(s). If this was someone’s pet, they may consider having one of the heads removed. Most of the body organs are far below the neck area. So the one remaining should be able to survive. That would likely be an expensive procedure, and the patient(s) may die. Since this is not a pet, nothing is likely to be done but study the survival habits of a conjoined serpent.
A copperhead is NOT a pet.
They don’t do that.
If they survive, normally one head is dominant.
Sometimes, both heads function normally and they just feed them both.
Lots of corn snakes pop up with two heads.
Quite a few survive it.
People are worried about a “double bite” but with two heads, its aim is gonna suck, anyway.
