For sex determination in laying quails there are several methods:
Based on the breast coloring you can
determine the sex in many color varieties very early (week
3). Hens have a speckled breast.
On the other hand Roosters have a non-speckled breast.
With some color varieties this identifying feature falls off, because it has no color varieties speckles. Similarly, there are examples in which the breast color is not clear enough to determine the sex. Here it should be made the cloaca test at week 5/6.
When cloaca test (available from
week 5/6) Is the quail turned on his back.
Behind the cloaca is a small knobby to feel.
with light pressure on these knobby, flows a little
foam from the cloaca at the rooster. in the female
lacks this foam. This is not to cum,
but a foam which is to close the cloaca of the hen for a short time, so that fertilization attempts by other roosters are less successful.
In groups with many roosters, which are together since hatching, it may happen in some cases that roosters do not train their attributes, so do not even foam, but this is rather the exception.
Who is still inexperienced, or has animals which one is quite uncertain, may observe
If an animal "crows" it's definitely a rooster.
Pedals an animal an another, it's a rooster, the other a hen (while pedaling, the rooster keeps the hen with the beak in the neck and tried to bring his cloaca to cloaca of the hen).
And finally, who lays eggs? The total number of eggs can be close to the number of hens (Note: quail can also lays two eggs a day set (distance 16-20 hours in summer).
