I've been wondering about this since Harley's shed issue, and now my parents' rescued rat snake is making me wonder again. So, when Harley had her emergency sheds, ALL my other snakes shed very close to that. Having another 2 year old, a yearling, and a 13 year old, that was a bit of a strange coincidence since they all have very different shed schedules. And this happened twice during her whole skin ordeal.

I was talking to my mom tonight, and the ratsnake they rescued is going into an emergency shed (has been blue for a few days, so I believe the 'blue-belly' phase was probably about a week ago). Well, she said both their blacknecks (which share a tank) have gone blue and shed within the last week or so.

That leads to my question... Has anyone else noticed anything like this? I don't think it happens normally, but I was wondering if there's some sort of hormonal feedback going on during emergency sheds. I imagine the snakes would be producing a lot more of whatever chemicals signal shedding to induce an emergency shed, and maybe that's enough to trigger sheds in other snakes?
I was trying to figure out what good this would do in the wild, and the only thing I could come up with is that normally snakes aren't in close proximity, but if they are they are pretty much on top of each other. If one has an infection or something that triggers and emergency shed, it might be beneficial for the other snake to shed soon before any sort of infection had the chance to become advanced.

idk if this is just coincidence, but I'm definitely going to look for this if mine have emergency sheds in the future.
