ive read stories about exploding eggs and even thought id come across one (last hatch one egg was 'hissing' and oozing so i threw it out, it was full of putrid runny yellow/brown liquid) but today i came across a totally different rotten egg. all eggs hatched yesterday barr this one, and momma hen had started peeling the shell off so i took it away to inspect it. it was a heavy egg so i presumed a chick was in there, but saw no movement so decided to do an eggtopsy to see what went wrong. i first carefully peeled the shell off to find the membrane intact...hmm chick didnt get so far as oo pip the membrane i thought. i could see something solid and coloured under the membrane so went to peel that off. and here i was struck with the worse smell i have ever smelt in my entire life (worse than the liquidy-goo rotten egg) i was instantly heaving. inside was a solidish mass..only comparable to cottage cheese. it was blue/green/white in colour. no sign of any yolk or 'normal' looking inside of egg bits. just green/blue/white cheesy stuff..was this then a true rotten egg or did something go terribmy wrong somewhere down the line????
