So if the colder temps are increasing the male hatch rate by decreasing the female hatch rate.....I wonder what kind of hatch rate Cjarvis gets?

This Girl is quite lovely!!

i had always heard the hen determined the sex- so temp fluctuations now make me wonder

does anyone have cochin, orps, or wynadotte's laying? I have a silly broody

Thanks, I had a huge preditor attack that killed nearly all my flock about a month ago. She (Jackie O) was the only true survivor of the attack. The others that survived were in a different area, she was in the area of the attack and got and stayed up high and survived w/o a scratch.

@artsyrobin from my research female embryos are more fragile than male embryos. So anything that causes stress on the eggs can swing your male ratio higher than the female's, like cooling the eggs in the fridge for 1-2 weeks. One study looked at exposing several hundred batches of eggs to different ultrasound wavelengths including a "control" group. It was very obvious that the stress of constant exposure increased the survival of males versus females.

It isn't that the cold determines the sex of the egg, it is the stress (in this case cold, but any other stressor will do it too) that kills the more fragile female embryos, leaving more % of the hardier male embryos to hatch. Same thing happens w/ a stressful incubation (to hot or dry or incubator gets to cold etc..) more males will survive the assault then females. (at least that is what I have seen posted many many times on other threads and sites)

Okay, so somebody knowledgeable in this Shawnee show-thing please fill the rest of us in. Do we need to be there early to have a shot at getting some of the sale birds? Do the sales start later? Shelbydog and I aren't showing, but we'd like to maybe pick up a decent breeding bird or two.

The sale birds will be in the sales area, typically the owners name and phone number is on the coop. Earlier is the better birds as they do go quickly however do not expect an answer when everyone is still cleaning their birds up, touching the birds up or while the row the birds they own is being judged.

That is correct Kass, I just did not want to sound sexist by saying it that way, it is much different coming from a woman.

60% is normal for me with cold eggs, when I set weekly and store them at 65 degrees I get 90+ % . There are a few tricks I have learned that also seem to increase the odds of one sex or the other and they do seem to work well.
I know when I use a considerably older cock over young females I get a very large number of females and when using a young cockerel I get more males. When the birds are very close to the same age it is about equal. Its ran that way for me for quite some time.
I know that that makes little sense though as the Male in the fowl is ZZ while the hen is XZ so the hen truly determines the sex of the offspring.

Too cold for me outside. I'm in for a second cup of coffee and a dry pair of socks. No school in Muskogee today because everything that melted yesterday turned to ice overnight.
My flock seems cranky. They don't like the cold, but a few are developing their flying muscles. They fly from high, dry spot to high, dry spot. One of the packing peanut capons chose my shoulder as a high, dry spot, and he stayed there for three trips into the barn and two trips into the house to defrost water buckets. On the second defrosting trip Therese and Agatha (house cats) realized the chicken was not a natural part of my jacket, and they started circling my boots, calling to the cockerel, and making "Come down and play with us" faces. As soon as I got outside, the cockerel rejoined his friends. I think the cats spooked him. He is used to the barn cats, since they ignore the chickens. The house cats were too attentive. I think they would have enjoyed a nice game of cat-pile on the chicken if he'd left my shoulder while inside the house.

A boy after my own heart lol! What a nice personality

1st come 1st serve and you best be quick! Black Friday has nothing on a bunch of Okies at a chicken show.
