I was hoping to have some pretty eggs like that between my Cayuga's and Buff but they decided they wanted to by males so I couldn't have eggs

No. Out of the 30+ eggs I attempted to hatch and failed miserably at I ended up with 5 ducks and in November they were ALL running around with cute little curled tail feathersYou have no females?
Man that’s a sausage festNo. Out of the 30+ eggs I attempted to hatch and failed miserably at I ended up with 5 ducks and in November they were ALL running around with cute little curled tail feathersI must have some bad juju when it comes to ducks because the main reason I wanted them was for the eggs!!! HAHA jokes on me!
its common not to beleive it, but alot of people beleive enviromental factors can increase the chances of males hatchingNo. Out of the 30+ eggs I attempted to hatch and failed miserably at I ended up with 5 ducks and in November they were ALL running around with cute little curled tail feathersI must have some bad juju when it comes to ducks because the main reason I wanted them was for the eggs!!!

That is very interesting. And good to know it may not be my juju. Haits common not to beleive it, but alot of people beleive enviromental factors can increase the chances of males hatching
The thaught being that male embryos are stronger and more likily to hatch. So things like putting eggs in the fridge or incubating at hotter temps could hatch out more males. Not that we would on purpose but it could happen accidentaly. I dont beleive this
BUT research tells us that unlike humans the female bird decides the gender of the embyo by giving both sex chromosomes
"In humans, cells in females have two copies of a large, gene-rich chromosome called X. Male cells have one X, and a tiny Y chromosome.
Birds also have sex chromosomes, but they act in completely the opposite way. Male birds have two copies of a large, gene-rich chromosome called Z, and females have a single Z and a W chromosome. The tiny W chromosome is all that is left of an original Z, which degenerated over time, much like the human Y.
When cells in the bird ovary undergo the special kind of division (called “meiosis”) that produces eggs with just one set of chromosomes, each egg cell receives either a Z or a W."

That artical goes on to mention the fact that many wild bird species hatch 1 gender more than the other
Ive heard old stories about someones favorite hen who hatched mostly females, and poor ones who hatch mostly males. I havent hatched nearly enough to form my on stats on it.
But i do feel its possible through generations of selective breeding to breed a hen whos hatchrates favour females. it would take armys of ducks and ducklings and incubators and people and notebooks
Queen bees also decide the gender of the eggs they lay by laying a fertilized egg (female) or unfertilized egg (drone). Fascinating how some animals can do this. I bet some of Henry the 8ths wives had wished they could do thatits common not to beleive it, but alot of people beleive enviromental factors can increase the chances of males hatching
