please help with eggs

[dulce]

i put 40 eggs in the incubator 15 hatch. i candle the rest of them 8 looks like there is something in them so i put them back. the other 17 was clear so i crack some of them open and it looks like some were fertile so my question is do anyone know why some of those 17 did not keep going. i have them in a sportsman 1502 incubator. the temp is set at 99.5 and the humidity is set at 60. i would like to know if there is any thing that can be done or am i doing something wrong. i have 80 more eggs in the incubator so any help would be great.

Hi

Here is an article on incubation failures ~ https://www.backyardchickens.com/a/egg-failure-to-hatch-diagnosing-incubation-problems

There are many things that could cause the eggs to quit developing. 60% humidity during incubation seems a little high. For me 45% is best so the eggs lose enough moisture and the air sac grows adequatly. Then at lockdown on day 18 I put it upto at least 65% for hatch.

Good luck with your next batch of eggs

So many different variables in eggs not developing. Were they shipped? Did the temp spike? Did the temp go down for a while..power outage? How was the humidity? Once you get a few hatches under your hat..you will know what's up. That's a great site to go to Yorkshire posted. Ask questions here and there. But I think the best thing..is that experience ..under that hat.

We tend to find, that certain things work better for us than others. Different environments. And...etc.!
