6th Annual BYC New Year's Day 2015 Hatch-A-Long

Well two looked like there were not as big inside the egg as the rest..i could see more light thru the liquid part of the egg then the other, the others were just all dark for the most part but all the aircells look to be the same size relatively. The one that hatched looked all fine and normal on day 19 and then on day 21 the aircell was huge and the egg felt really light.
 
Questions often come up about the likelihood of pullets vis a vis cockerels in a hatch so I thought I'd share something.
Yesterday,my son was riding with me after he dropped his car off for repairs.
We were talking about selling some chickens. He asked if chickens are hatched with a 50/50 chance of being pullets and cockerels. I said yes. He did a little math in his head and told me there's a 1 in 5,000 chance that a dozen incubated eggs will either be all pullets or all cockerels.
He's in college for actuarial science. The exact number was closer to 4,990 something but he rounded up.

Wow very cool.

I had only once ever since I started hatching have a broody hen hatch 8chicks out of 9eggs. ALL 8 chicks were pullets!

I don't expect that to ever happen again lol but I did witness the occurrence once.
 
Doesn't the hen carry the gender.... The gene that decides the genders is carried by the hen so the hen that has pullets more often will usually have pullets more often?

Interesting anyway... Out of seven buff orps I got six pullets and one male. And only time will tell but I'm testing out feather sexing and it looks like my Bantam hen had three pullets... three for three.

Yes, that is true and it does happen that a hen will lay more eggs that are female sometimes. Averages work over large numbers but there can be a lot of variation when looking at small samples.

I have had one hatch of all pullets. I have not had any hatches of all cockerels yet though.
 
Here's Oops and Solo, the only 2 out of 41


It is A LOT more quieter in the house now that the second chick is here, although on occasion Solo still sounds off with the alarm peeps. (Probably a roo)
Aww..I clicked on the photo, and ..check out that eyeliner. I love that.
 
My first chick hatched last night!!! He is so cute and vent sexed as a male. 5 more eggs need to hatch, i assisted the first guy because he was more developed but he was shrink wrapped bad. i think it was because he had a very porous egg shell. Humidity has stayed almost constant at 55-70%. Today is day 23(24 really but two power outages put them behind).

Happy for you! I hope you get more! Power outages, and you still got a chick!
