Serama Eggs, is 19 days to hatch true & why?

Yes, as a matter of fact I put an a couple eggs in the oven at 450 degrees, 18 hours later I had 10 cute fuzzy butts.

No, joking, but it is affected a little. Not too much.
Im not sure if its just a Serama thing, I think its most banties.

My cochin chicks usually hatch at 18-19 days.

I have a flock of japanese bantams and they have hatched in 19 days. I also think it is because of the size of the chicken. They just don't make you waite as long.

What weight in an average Serama egg?

Yes, very much. Lower temperatures makes the chicks hatch later and higher temperatures can make them hatch too soon, usually with bad results.
I've had an experience earlier this year with a stupid broody who wouldn't commit. She'd sit, get up, sit, get up. Her chicks hatched over quite a long period and we lost quite a few of them. The last one hatched after 5 weeks! She survived and lived 5 months before health problems, probably as result of the long incubation period, caught up with her.

I have researched incubating temperature (99.5) and humidity (54) for my first ever (I started them tonight. It is December 18th) hatch of my Serama chickens. I chose instructions for hatching quail as the birds and eggs are similar in size. I am journaling my experience as a reference point. Please pray it all goes well and smoothly.

Hi Anna, and welcome to BYC!

That sounds good!

Wishing you a great hatch!

My 10 year old daughter uses her little Serama hen for showmanship. She was champion in showmanship at her county fair.
She told the judge that Serama eggs hatch at about 19 days. The judge asked why this was and she honestly told him she has not been able to find out why. This was the only question she could not answer.

She has searched online, including here, and finds various vauge reasons, not really sure if any are correct.
Some say it because they are so closely related to jungle fowl, others because that need a higher incubator temperature.

There are other breeds that are breed from jungle fowl and don't most chicks hatch a little early if the temperatures are increased.

She has a show this next weekend and is also going to crossroads, she wants to find a solid answer to give the judge. Or, is it just not true?
Thanks, Gabby is hoping for help on this!

Tell Gabby that it's one of the idiosyncrasies of dealing with bantams. I've had Nankin bantams for years as well as a handful of d'Uccles. Nineteen days is the standard for bantam clutches, regardless of temperatures. The only times I've had eggs hatch later is either when the power went out on the incubator for more than 12 hours early-0n, or when another hen made a "late deposit" to the nesting box.
So - standards are generally 21 days, bantams are generally 19 days. There may be small deviations (my Jersey Giant's eggs always went 22-23 days,) and like babies, some are more reluctant to enter the big, wide world, but most stick pretty closely to their "factory programming."
