Males or females?

[Aqwifey]

I'm just going to go through the head shots. The vents are mostly stretched out, which makes it hard to tell the shape, though the first and last ones looks male. The one titled "Lighter brown" looks like a pretty prominent bulge under the vent, which says male.

Head 1 - male
Head 2 - probably female
Head 3 - probably female
Head 4 - Need to see this one's chest as well, but probably female
Head 5 - male
Head 6 - unknown
Head 7 - probably female
Head 8 - not feather sexable
Head 9 - not feather sexable
Head 10 - not feather sexable

Okay I was trying to more the feathers away to see the vents I know 2 at least are making crowing sounds the lighter brown one is the one crowing every 10 mins.

#2 looks like a recently bred female to me. Can you post pictures of their heads and breasts?

I was also going to suggest that quail2 could be female.
