Burrowing Boas??

[Beardonicus]

Hey everyone. I picked up 2 baby male BCIs at a show this weekend and they are my first red-tails. I went to check on them last night after they both ate a frozen/thawed hopper mouse for me .....and I couldn't find them! I finally saw a little black speck in the aspen and behold! They had both burrowed under the aspen and had only their little noses poking out! It was pretty funny, but I was wondering if this was normal behavior for babies? Any thoughts?
