August Hatch along?

Day 21
No change.
Even though I knew there would be delays from the power outages and the temp drop a few days ago, I'm still bummed. No peeping, no rocking eggs. Nothing really to show that hatching is close.
The only good thing to the delay is now my weekend is coming up. I was afraid they would hatch while I had to go to work. Hopefully they will hatch in the next 3 days. :fl

Let me see if I can help shed some light. You've covered the possible issues of insufficient turning and small end up or down as well as egg storage time and handling.
If your temp and humidity are guaranteed to be accurate, that rules out high humidity and too high or too low temperature.
Retarded development can be a cause of malposition and likely in your case since some of yours are behind the rest.
Other possibilities are old breeders, round eggs, very large eggs and nutritional deficiencies - especially vitamins A and B 12. The latter causes a head between thighs malposition. An excess of selenium can cause malposition too.
Lineolic acid deficiency causes slow development and 75% end up with a head over right wing malposition.


That again could be a fatty acid (lineolic acid deficiency) and the retarded development contributes to malpositions.


97 will delay development by quite a bit.

They should be fine unless you only have one or two chicks.

ok will do some investigating then,the hens are year and a half now and the rooster is 2, they free range in the yard and are on Purina laying crumbles feed with free choice of oyster shell and cracked corn, they usually don't bother the garden but lately have been after the tomatoes, they get a couple hand fulls of meal worms for 7 hens and a rooster daily besides vegetable peels when there are some to be had and about once a week they get their favorite treat of garlic. will look into getting some viatamins for them then. Besides trying an egg turner that has the eggs laying downn. Thank you for your advice

the eggs were from my flock.... I have sold all but one of the hens that were old enough to lay. I have several upcoming that I think are hens, and I will have a choice of several Tom's.

here are some that were hatched out in july

A couple weeks before I am going to collect eggs for setting, I cut out all the scratch/corn. I want the bulk of the intake to be a fresh layer feed or grower/all flock if a rooster is present. Layer feed is adequate for producing eggs but may not be fortified enough to make vigorous chicks. Breeder rations are available but hard to find.
The animal protein treats like mealworms, fish, meat are OK.
For a nutritional supplement I use Nutri-Drench and dose according to directions on the label a couple times a week.
If I treat a non animal protein, it might be a berry like black, blue, etc. for the micro-nutrients.

I thought of a couple other issues that could be causing a protracted hatch and that is the ambient air and your elevation.
I see you are in Idaho. What is your elevation?
I assume your air is fairly dry most of the time.
I also assume the incubator passively draws fresh air from the room it is in.
So the temperature and humidity of the room can have an effect. The best we can hope for is an ambient temperature between 70 and 80 and moderate humidity.
If the incoming air is too cold, it can cause poor temperature uniformity which makes protracted hatches.
If the air is too dry, the humidification to achieve a correct environment can cause localized evaporation which causes cooling in those zones.
High altitude can cause additional problems if the eggs are from breeders at a lower elevation.
High altitude air has fewer oxygen molecules so they move around faster causing more diffusion across shell membranes which can cause excessive moisture loss. The lower oxygen further complicates the issue.
I hope you get it figured out.
I get a few malpositioned embryos from time to time but I think mine are from laying the eggs flat and insufficient turning.

elevation is about 4800 ft, these eggs are out of my flock no shipping and laid at same elevations, did a room check, it's about 70 and 30% humidity inside the room. Would leaving vent open the whole time help maybe?

I know it's a newer one for me the LG I'd gotten at cal ranch gives me nightmares still took me almost 2 years to try again after than one, I am also setting up after checking the other one out for cool spots before I set and this time using a incuturner for the hoverbator that turned a full one about every 6 hours
 
There's evidence that birds will adjust porosity of eggs with their elevation so since the eggs were produced at your elevation you should get generally good results by providing a little more ventilation than one would at sea level to increase oxygen exposure.
I would also weigh eggs when you start and periodically throughout incubation to insure they are losing weight at the correct rate. That way you won't have to guess on appropriate humidity. The eggs should lose 0.65% weight per day on average.
