Incubating different sized eggs together?

[Raptorchick]

Hello I currently have 12 serama eggs going strong on day 13 in my Harris Farms 6100 still air (with auto rotation). I've got four thermometers and two hygrometers inside, set directly between my two rows of eggs so I can maintain 100-101F and 45-55% humidity. This is my very first incubator hatch... so far everything looks great...
I went a little hatch-crazy, and just received 6 blue eggs and 1 olive/brown in the post. I have two other incubators, a Mini Brinsea Advance (holds 6) and a Janoel 12 (holds about 12).
One of the eggs was cracked pretty good, but wasn't weeping. I took qtips and gently swiped over the cracks with diluted hydrogen peroxide, then melted wax across. Both of the smaller incs lay the eggs on their sides, but the 6100 (which is dialed in pretty good) sets eggs upright, which would probably help all 7 of the shipped eggs.
Do the parameters in my 6100 sound ok to incubate "regular" chicken eggs? I think with the still air, I could place the eggs a bit away from the heater to keep them at 99.5-100.5F... and when it's time to lockdown the seramas, I can probably put them in the Janoel 12 through hatching.
I'm actually really unsure about everything at this point lol, does this plan sound reasonable? Or would you do something totally different? Any/all advise extremely appreciated

.. the wax burnt a little :/ I dont expect it to make it, but thought I would try...
Thanks ahead for any/all advise

I've got four thermometers and two hygrometers inside, set directly between my two rows of eggs so I can maintain 100-101F and 45-55% humidity.

In still air I set at 102... at the top of the eggs (floor is lower). Always move the eggs around inside the bator daily to make up for temp and humidity variations... it keeps hatches tighter and less spread out... I hatch different size and color eggs... I would go between 30-40% humidity... especially for colored eggs.

Happy hatching!

I think I would go with the Janoel for the cracked one to start, and place it on its side and hand roll, keeping the crack either up or on a side -- never straight down. At least for a few days to see if it develops.

Or - maybe you could strap it to a turner spot, on its side, with the smashed side facing up?

Good luck with the hatch!

Thank you thank you!! I've been rotating their positions each time I candle, which was days 3, 5, 7, 11. I heard that they shouldn't be candled frequently but couldn't resist I noticed the air cells growing unevenly on day 7, but thought maybe that was normal with incubator hatches? I'm glad I candled/moved them now lol... I like the idea of keeping the broken one separate and on its side, I've been afraid of hand rotating but it can't hurt to try. The eggs are 'resting' atm, to go in the incs about 5pm tonight... I think I'll put the cracked one in my mini brinsea, and hand-turn it on its side.. that way I have time to play with the Janoel 12 and get it ready for hatch
Thanks again !!

I candle almost daily
In the Mini, if you lay it a couple inches from the window, air cell pointing towards the window, pointy end toward the center, you can candle without opening the lid!

I don’t have a pic in the Mini, but this is in my Nurture Right.

To me... they will never be exactly the same... to many differences in the individual egg shells... some are more porous than others even from the same bird.

I really don't make adjustment to my humidity for individual air cells. I know what parameters WILL work and stay within them. My eggs are dark sometimes... I don't candle at all except enough to verify fertility and toss any that aren't looking approximately the same. I do enjoy candling my lighter eggs though... just cuz it's fun to see the life forming.

I think that first link is way too messy and hard to read, but it has some decent info, if you dig for it.
Thanks for that other link, I’m going to read it when I have some spare time. Looks like a good one at first glance.

The link from hubbardbreeder was super interesting ! I went a little cross-eyed on my lunch break, but wow the information. So many things to learn lol!
The serama eggs are more active than ever this is day 15 going into day 16, because of their development I'm locking down in the Janoel 12 on day 17. I put four blue eggs and one brown in to hatch, this is day 3. I rotated the seramas and the regular sized eggs, and candled in between... it's very early but I dont see anything in the colored eggs yet. I've also got one blue egg with the air cell on the pointed end, and one cracked blue egg in my mini brinsea, keeping humidity 35-40% and temp 99.5F, a bit lower than the mixed-egg bator, and they're marked for hand turning morning, noon, and night. No signs of life yet tho...
Thank you thank you for the help/info!
Pics of funny air cell candle below, I think it looks really porous too? :/ would that call for a different humidity, if it makes it? circle on the side is for rotating lol...

 

[WVduckchick]

Being extra porous could cause it to lose moisture more quickly. Just keep an eye on it. I usually go with the majority when I have a few porous looking eggs, but they seem to do fine overall.

I hatch Serama eggs all the time. In my experience Seramas originate in Malaysia where it is hot and humid. I keep my humidity at 45-55 temps between 101-102 depending on how many are in the incubator. Because the other eggs are a different breed they require less heat and humidity. I am not saying it wont work but perhaps you might have a low hatch rate. I am not an expert this is just what I do, lots of people have there own way of doing things. I also bring humidity up to 65% when they are in lock down in the brooder.
