Red foot egg question

Hey well heres the question, this is my first year breed multi female, I have two huge 13 inch females, and there eggs are about (to compair size) 1 1/2 chicken eggs, i got some new females and i just got a couple clutches , these females are
11 in. and they laid eggs about the size of pingpong balls, id say they are half the size of my other eggs . is this normal? im assuming that the smaller eggs will hatch out smaller babys? could it be the females are from differnt locations? I will take pics of them if you need to better understand the size differnce. all females are housed together and fed the same diet. thanks for the time and help.

oh one more thing, what is the recommended incubation temp? mine are hanging around 81-82.

one more thing again,

the clutch sizes for the big females where 8-12 eggs.

the clutch size on the smaller one where only 4-6

Sounds like a locality thing.Do you know where yours were originally came from?My cherryheads have never laid more than 3 eggs,but my Venenzuelans lay about nine.I guess the difference is the size.My cherryheads are no larger than 8 inches.My big ones are 12.

I know my big girls and my male are cb from columbian parents.

the other im not to sure about.

check these out.

I just found more eggs, 2 where bad. but got another four small eggs but these are more oval in shape. i think they are good becuse the two bad ones where brown and these four where perfect except for there oval shape.
