Is it an egg

[ooRachyoo]

i just got home and all 3 of my girls were tucking into something delish, so I went to investigate, they were eating what looked like an egg white no shell to been seen no yolk by the looks of things and all three laid an egg this morning, I don't know where it come from or what it was I've checked all their bums and everything looked normal, I'm a little worried something might be wrong
