So I couldn't help but candle the eggs tonight (day 11) just to see what is going on. This is my first ever hatching and I've never had a broody. Anyway, there were 12 eggs that seemed to be developing pretty well, dark masses in all of them, air sacs. I couldn't see any movement, but didn't want them out too long. Two eggs were bad, one was empty and the other was cracked. The smell was horrible. I am a little worried that the other eggs have been affected by this horribleness. I was out of town and this is the first I've seen her. The person taking care of my hens did mention that it has smelled pretty bad in the coop for a couple of days. I did not see any goop on the rest of the eggs. Any thoughts on this? Thanks so much!! I was thinking of just letting her sit and not candle again until the hatch. Is this ok to do? I also found a really porous egg, but it has a black mass in it, so I put it under her. Will this one explode? Thanks for all of your help!!
