Twenty-one days later was yesterday. Pinky was the first and when I checked the coop yesterday, lo and behold, a chick was on it's way. You would be surprised at the peeping inside the egg :)
Within ten minutes, after putting the egg back, the chick had popped the "lid" off.
Here's the chick about a minute or two old.
Last night when I checked her (and of course it has to be a "her") she was all fluffy & dry and snug under Pinky. I really am sure she's a she because when I spread out her wing she had all the same length pin feathers, a rooster has two lengths or so they say, I guess time will tell (and I hope I'm not backwards on this). This picture was taken this morning, and another chick was hatched in the night, so now we have two!
EDIT: Tracey left a comment that I was backwards with the feather check and she was right, thanks Tracey!
If you'd like to see the whole thing "live" I've shot a video. The egg is a bit blurry but the rest of the video is pretty clear.
