Dang I Thought I Was The Only 1 Running "roosterbators"

Good variety of parents.

I just noticed what Ken said. In birds, the females are the ones that decide the sexes, not the males.

saddina had posted something (don't remember where) about a study that showed female embryos are more susceptible to heat spikes, so maybe that's what happened? Did you have any heat spikes in the bator that might have 'cooked' your girls?

Shelly, I live and learn. I was applying the XX/XY sex determination system not the ZW. I wasn't aware that it existed, so thanks for making me do the research! I should have asked if they all were from the same hen, which is a very valid question. (At least in my mind).

I was following the thread where saddina was talking about high temps cooking girls. Very valid points and an interesting read, but I think in this case it's inapplicable because the OP Chickiechick said that out of 8 set eggs, 7 hatched and all 7 were roos. If the normal laws of nature applies then there should have been a basic 50/50 sex split, if it's a heat related issue, then there should be 3 to 4 roos and zero hens, not 7 roos. I think Chickiechick can't vent sex chicks at day one, and there is no shame in that, because most people can't. Including me!!!!
You may have to wait about a month like us normal people

Hi,

I've just read a question and answer page from the Texas Agricultural Extension Service, The Texas A&M University. and this question was asked:-

Q. Does incubation temperatures influence the sex of hatching eggs?

A. Incubation temperature has nothing to do with determining the sex of the bird.Altering the incubation temperature will only reduce hatch and health of the birds.

I just think Chickiechick has just had bad look in getting all males, it happens.

In my colour breeding experiments, I only breed from pairs, eggs are incubated and resulting chicks are sexed, very often there are more males, in a few occasions I've had mostly female.

Yes, I thought it was odd too. 7 roos out of 7 hatched from 8 set. The odds must be astronomical

I cann't imagine vent sexing bumble bee sized day old button quailies. I can barely stand to pick them up to move them I'm so afraid I'm going to break them. Squeeze their rears to peek at their privates with a magnifying glass

I don't think so

I may give it a try with the coturnix if I ever get enough hens to lay eggs to hatch ( darn 'roosterbator'

)

well i have heard when there is population disparity (more males to females) that mother nature can have a way of fixing it. i know after i sold most of my birds last year for a time i wound up having 5 roos and 3 hens in one pen. out of that bunch i incubated 90% females. its weird but i never quite have gotten chicken genetics i just enjoy the heck out of hatching them
