Day 10, no veins, possible temp problems - Page 2

post #11 of 15
I don't know about the temp question since I've never calibrated. But in my experience there would be some growth of it was a fertile egg even if the temp was a little lower. You wouldn't just be seeing normal eggs inside by day 10 even if it was 3 degrees off. They would be struggling, maybe some blood rings and if it wasn't fixed a low hatch rate. I would be confused if I were you if you say they are infact fertile. I have a hovabator and don't have any extra temp checking devices and have had 3 100% hatch rates none being perfect humidity wise. For instance my humidity drops every night to 20ish and I fix it in the morning. It's either sonething really off with your incubator or the eggs are not fertile

Ok, I have done some checking. My thermometer seems to be accurate.

I checked fertility and 100% of the eggs I cracked (new ones I had gathered in the last couple days) were fertile.

I finally candled all of the eggs (I had only candled a sampling before when they were all clear I gave up) and it turns out 7 of them had development and 4 of them were moving (the other 3 might have been asleep?) Those 7 are all still in the bator. I kept 2 of the clears in the bator as a test because it wasn't day 14 and people said not to throw out duds until day 14. I cracked all the rest and there were a few blood spots and a few clear spots on yolks. But no veins or blood rings or anything. So as best I can tell it seems we had some problem the first day or two of incubation that killed off a bunch of embryos. Does that sound like what may have happened?

So right now we are completing the incubation with those 7 eggs because they only have a week more. Then we will try again with a new batch of eggs.

That's good news you have some that developed! I think since there are some on track that means the others either were not fertilized or had an early death too early to be a real blood ring. I had 22 in the bator and day 10 I culled 6 that were blanks- infertile. Surprisingly they can actually deny sperm from a rooster even if they are mating and the egg wouldn't be fertilized.There can even be eggs in the same few days from the same hen and not all are fertilized. Atleast I read this on here. So maybe there was a hen or two who decided not to accept and fertilize even though a lot of the others were. Every egg I have cracked prior and after has been fertilized so like you it is strange to have some not grow at all etc. But I don't think it was something you did- since others a good. More likely just a weak egg. Are your hens young? Do you have more than 1 rooster? It is exciting to get to day 14! I'm on day 13. Even if the chick is resting if you lightly flick it a few times you should see movement or some sort. Re check it a few hours later but you will most likely be able to tell if it's alive on day 14. They still have space in there to move from my experience

Update - all 7 of the ones that had developed hatched! They all hatched at various times on day 20. They are all alive and well, peeping, moving eating and adorable smile.png
We are starting a new batch tomorrow.
