As you may have gathered I am just starting out with a view to rearing Japanese Quial for eggs. I have read various ratios of Males to Females 1:3 seems to be common. So what happens for the remaining male chicks...I guess the same question applies to the entire poultry industry. I have just done a quick calculation based on feed costs here (22USD per 50kg bag) and it is probably not viable to fatten them up to sell for meat.
Is there a way to get more females than males from the eggs or is it generally 50:50 as you would expect.
Thanks
The quick answer to your question, is no, there is no way to increase hatch rates to produce more females than males. The answer to your question, "
So what happens for the remaining male chicks..." is misleading. Some varieties (like the tuxedo or A&M) can not be correctly "sexed" until they fully mature, so it's not like we are euthanizing baby chicks. Only when they are mature and at a decent weight do they get harvested (or matched up with 3 or 4 hens for hatching eggs).
There has been a study about increasing male production in poultry (for broilers) since some reptilian species have been proven to produce more males when the temperature has dropped a few degrees at a certain point in the incubation process. The debate on weather this same theory holds true with poultry has been going around for some time. About 2 years ago,
TwoCrows provided a link to a study that first introduced the concept that it could be possible for poultry to produce more males than females with a drop in temperature at a set time in the incubation process (I've searched for an hour, and it was 55 minutes longer than I wanted to search). I don't know if the reverse has been considered for producing more hens, but almost anything is possible.
Unless you want to hatch your own eggs, a good ratio would be 0:4+ (a roo isn't required for a hen to lay eggs). If you plan to consume the quail, then there is no wasted feed (compared to culling a roo and and tossing it in the trash, and shame on the owner who does that). Also, most of us will observe our males for sign of aggression and other negative traits that we don't want to be carried to the next generation.
