Could it have been just a weird looking meat spot?I didn't take any . It looked like a small white worms likeaggot with a head like a maggot (brown spot on end). Eggs have been sitting on counter for a few days...It is cold here, no more flies, and the egg didn't look damaged.
I tried it only comes up with maggots ON chickens or in old eggs. I thought oh no my chickens have worms but that's not what worms look like. Not a meat spot. It was white about 1/4" long, squicky just with what looked like a head and tail.Maybe google it and see what comes up.
