I put them all in on Sunday evening last week. Yesterday was the day I cracked one and could see a tiny heartbeat. Today I candled (I know I SAID I wasn't!) and I could see spidering of the veings, and a small embryo forming. You couldn't see the tiny dark spot candling yesterday. I was googling and someone had pics and theirs looked like this on day 3...are mine going too slow? I think my temps have been a little low because its really cold in the house. Is there any chance they will make it if I keep the room warmer to keep the bator temps up?
