Question about shed

I wasn't really sure what to title this thread so I went for the general theme.

All of my BPs are fed on the same schedule. I offer food every 6 days even if they are about to shed. Well, it seems like they all want to shed at the same time. Almost every snake I own either just shed, is about to shed or going blue. Even my boa fits into this time line kind of. She shed last Sunday and she is not fed on the same schedule as my BPs. I'm still waiting for Nova to shed, she just came out of the blue yesterday. And all but my 2 pastels are in the processes of going blue. Has anyone had this happen before? This is the first time this has happened so I'm pretty sure it's just a gaint coincidence, but it's still weird.

Sometimes, all of mine will shed within a few days of each other. I suspect it has alot to do with being on the same feed schedule.

I rarely have more than two shed at the same time. I feed all but one on the same day each week. I believe they just grow at different rates just like every other species of animal.
