when i first saw it i just assumed it was an egg with a soft shell but when i picked it up it felt solid though softish to the touch, kind of like rubber maybe. and on the inside didn't look egg like to me at all. the outside did sort of look like a soft shell in parts but the inside? hard to describe. there was some clear fluid amongst harder stuff. didn't smell too pleasant either, not a strong smell or anything though, had to hold it up to my nose to smell anything at all. kind of like old seafood maybe? i have absolutely no idea what it could be. she seems fine, had a loud sing after laying it and wandered off outside. yes, the charming lass laid it on a pillow next to the couch in our sunroom so that's how i know who it was any info or help would be greatly appreciated, thanks!
