i had a small clutch of boas born on the 28th of May, much to my surprise. anyway, 2 of the babies still have not shed. they've eaten twice but no sheds. the only reason they've only eaten twice is because i was under the impression they would not eat til shedding, this is my first clutch. i have them in a container with wet paper towels, a bath and rough objects to rub on and start the shed. sometimes it looks like they are rubbing but nothing yet. should i be worried? any advice?

thanks,

chip
