Ok, i wasn't mad lol, theres a bit of noise coming from the egg and it moved a couple of times!
At first i thought i was actually going mad, as the egg looked like it was vibrating? But thanks to another thread i read on here it apparently means the chick is getting ready to pip. Never seen an egg vibrate on the spot like that in my life, but hey, this is all brand new to me :)
So, i guess i'll get back to work and keep a close eye on the egg Yay!
