Incubation starts within and hour of the heat getting to it. The eggs will hatch in about 504 hours from setting them. Use google to add 504 hours to the day you set the eggs and see what day that is.
Sorry for your loss.So, just to update. The two chicks I was holding, Agent 13 and Coulsen, slowly strengthened up and are now under their mothers (Coulsen being a bantie is with the other bantie chicks under Princess, the other under Susie). Coulsen turned out to be a blue silkie mix, which means that he must be related to Azul.However, not all has gone so well. I'm feel a little down in the dumps because I spent all night and morning spending all the energy I could helping these two chicks and when I finally got them outside with their mothers things began to go down-hill. I went to check on the three remaining eggs in the incubator. The one I was pretty sure was dead I opened and found the chick fully formed but drowned. I believe it was upside-down in its shell. The other had a live chick that had burst free but was gasping and bleeding. It too drowned soon after, even though I tried to help it. The precious thing was named Green Arrow. I tried to bring him back, but it was too late. He too was upside-down in his shell, just as Coulsen had been. Canary is the last egg to hatch and I think she is side-ways in her shell, so I'm assisting her very carefully. I have a feeling I'll be spending time up awake again tonight. I can't tell if she is ready to hatch or not, even though I can see her belly. Its hard to tell if the yolk is in the belly or outside the belly when looking through a semi-opaque membrane. Finally, just as I was getting over loosing those two in my hands, having washed their blood off my fingers, my mother comes in and tells me that one of our dogs, who loves chicks but has hunting instincts, found one of Princess's chicks escaping and caught it. He brought it to her and it died in her hands. It was my favorite, little Snart, the strongest and healthiest of all of them. I kept petting him, praying he would just wake up, but he never did. It was terrible. I showed him to his mother so she would know he wasn't coming back, helping to get the other panicked chicks back to her (one was escaped, as it slipped right through the chicken wire, and the other was the weak chick that couldn't keep up with her). I then buried him under a tree out in the field. I didn't end up helping Buttercream's leg because she is getting around well, even preening herself, and I didn't want to disturb Susie anymore then she was already disturbed. I'll have to work on that tomorrow though. It feels good to have people who understand, so thanks for listening.
Rest in peace little Snart. Rory's going to miss you.
Lol I can only imagine...I think my husband is scared...he's not new to hatching chicks but I was just gushing about my crazy excitement for our first hatch together and he's looking at me with that "oh you poor dear...what have I gotten myself into now??" look!!
Plus he's been caught with his hands in the brooder when he thinks no one is looking!! The look of a kid caught in the cookie jar 
It'll be fine!
My other half pretends to be not interested in them but I've caught him often enough chatting away to chicks in the incubator
He's a secret chick addict!!
If you get Bellsouth Hatchabatch on your phone, it starts day 1 the second that you add the new batch on the program. It also counts for the fact that no real development is seen until 24 hours after adding the eggs. Therefore, it has a candling reminder on day 15 (14 days of development) and lockdown reminder on day 19(18 days of development). So, no matter how you count it, it is still 21 days of development.
I downloaded that app!!!! Love it!
They look half plucked here
