EDUCATIONAL INCUBATION & HATCHING CHAT THREAD, w/ Sally Sunshine Shipped Eggs

Incubating upside down increases malpositions. Also, keep in mind that each egg is different - this last series of hatches, I had eggs from two groups of chickens, and for whatever reason, one set lost weight SUPER fast compared to the others (they were very dark marans eggs, should have been SLOWER). Not porous, but (older) pullet eggs. It was so bad I had to move them to a separate incubator at around 8 days and do the rest of the incubation for them at 60%+ humidity (vs. 30% for the others). It's an extreme example, but it happens. (All but one hatched, happy ending.)

I weigh the eggs before setting, and when I candle, and I have a spreadsheet that helps me calculate the % weight lost vs. expected. Several of the ones that hatched had >20% weight loss.



Ugh. Ow. :hugs



I'm s
I have a couple of double yolkers in the bator. Most don't make it. I have hatched several though, though usually only one chick survives or is even alive.

So last night I see a pip in the DY. Thinking it would take hours to zip and probably eventually need help, I forgot about it. 4 hours later the shell is empty and there is just one huge damp chick with a HUGE belly. It can hardly walk.
Seems like chick #2 probably died and is inside chick #1.
I have suspected that this has happened before.
This morning it is just fine, waddling around.

Wow, didn't think of resorbed twins in chickens!
