candling, is this normal and a good sign??

[lottyloo]

I candled a few of the eggs i have under two broody's this morning while they were both out eating breakfast and noticed in a few eggs that when i held it up the the light there was a dark (about 2cm blob) that seemed to float to the top, is this the air sack/devoping chick? or is this something bad?

How long has she been setting on the eggs?

It wouldn't be the air sac, that is stationary, at the large end of the egg.

Good luck!

the blob could be the yolk, veining would be the best indicator of growth

oh i have not seen any viens yet, ive only been using a bright light bulb in the coop to candle so i'll take down a bright torch tomorrow and see if i see anything more... they've both been on the eggs for 4-5days (i suppose its still early to tell if anythings happening, maybe i should wait till about 10 days to see if there is any veins forming)... Thanks guys
