not so good hatch?

[harris farm]

I had 16 green eggs from 1 americana hen. They were small eggs and 8 were from the fridge. In all, only 4 hatched and 2 had problems. They could not stand up for any time. Just laid on their sides. What causes this. I help them up, they fall over and jump like popcorn.

How old are they? Newly hatched chicks are tired.

Did all of the eggs develop? Did they just not hatch? How was your temps and humidity.

How old were the eggs?

Temp and humidity were good the whole time. 9 eggs were infertile and several eggs went full term but never hatched. and the 4 that did hatch were 2 days late. They were 3 days old.

It sounds like your temps were low. You need to get a different themometer or check yours.

16 eggs from 1 hen means you collected for nearly 3 weeks. That's too long for good results. Some from the fridge means that some were kept too cold. Some not in the fridge may have been kept too warm. 50 to 60 for up to 2 weeks ( 1 week preferable) if all other conditions during the incubation were perfect your results may have been better.
Sounds like the egg prep was the issue.
Also, I believe that when storing they should be turned daily.

Rooster fertility, roo, hen ratio, breeder age, daylength, parasites, nutrition and MANY other things play a role.
1+1 does not always equal 2.
