If the temperature is dropped by a few degrees for three days during the embryological development of a freshly laid egg, some chickens which should hatch out male instead become female.
They have the genes and chromosomes for maleness but they are fully functional females able to lay fertile eggs. If they are then crossed with normal males, the resulting chicks are all male, said Professor Mark Ferguson of the University of Manchester.
This is what interests the poultry industry. All the female chicks which hatch from the breeding stock which provides the broiler chickens we eat are destroyed after hatching. Only the males put on enough meat, at sufficient speed, to make them economically viable. So there could be large savings if the breeding stock could be made to produce only males.
Conclusion: Raise Temperature to 99.8-101 for Female and lower the chance of Males for laying hens.
95.5 is a good Temperature if you want mostly Males for Fryers and utility purposes. Good Luck: from Lauren Dayton, TN.
