Good morning, ladies! I don’t know if I’m posting at the right spot. I need some help!
I have a single Mystic Maran/Welsummer or Polish mix egg that is on day 25. I’ve kept the temps at 99-101 the entire time, humidity I kept in 50’s for half the time until I read more about dry hatching specifically for Marans, and I immediately switched to upper 30’s low 40’s and I was able to lose 9% of the overall weight of the chick by LD on day 18. I also read that Marans can delay hatch until day 22/23 so I wasn’t too worried. Well, a couple days into lockdown I realized that my incubator has been dipping to 96-99 maybe the entire incubation process.

The temp is faulty on my friend’s farm innovations incubator. She let me borrow it and I thought it was strange that she was only getting like 16/24 easter egger hatch rate from her own eggs! And now I think I know why!
All that to say, this little guy pipped internally yesterday morning (day 24) and I was just kind of all around nervous because of finding out my mistake. And wondered if it would delay the hatch longer. I put a safety hole which ended up right next to the beak, and he’s helped peck a bit away from that hole but not very vigorously. So, I picked a couple of loose pieces of the shell off so I could see his beak and observe the beak movement as he pecks, and try to get an idea of the positioning of his body. He is definitely still making eating motions from what I can tell. But sounding a little more frantic when I pick him up. Like he wants to tell me something. I’m gonna give him some more time but this morning I don’t see the veining I did last night. But he hasn’t tried to turn at all. Does that only happen once they start to zip? Is he just waiting to absorb the yolk? And does that give them a burst of energy to get out? He’s not rocking in his shell or seeming very energetic to get out. But vocally a little more energetic. Just moves head and beak back in forth like eating but not like he can get out. I guess I’m worried that because of the incubation trouble that he’s not strong enough to break out.
I am perfectly comfortable with helping but I don’t want to start too soon and nor wait too late. I read your article on detailed assists. I just wondered what steps you would take at this point. Internal pip was around 9-10am yesterday day 24, it was around 3-4pm when I made an air hole and around 7:30pm last night when I helped peeled a few pieces it had pecked against away to see it’s beak. I’ll show you what he’s accomplished so far, not much through the night. When I peaked in last night to view the beak, I could see some veins on it far back in the shell last night so from your post that means it’s still absorbing the yolk. It’s 9:30a est on day 25, obviously but fits with what I know now about temps for it to delay a bit. How would you handle this? Should I give him all day to try to start zipping? I’m afraid he’s starting to look shrunken a little? Maybe you can tell better than me. Should I go ahead and put coconut oil in there? Any direction or red flags to look for would be greatly appreciated. (I have 6 more Marans due to hatch in 3 days, and 10 welsh Harlequin in 4 days.) This one is my very first and only one at the moment and I’m feeling like a basket case!
ps. I had read about sanding down Marans eggs so that you can candle better, but also making it thinner for these chicks to break. I wait until lockdown to reduce risk of infection but we will see. You’ll see in photos.
