The easiest way to tell male and female quail apart is to examine their chest feathers. Females have a speckled chest but males are plain and paler.

When we bought our quail, one was definitely male, one was definitely female and the other looked like it was developing the speckles so was considered a possible female. Unfortunately the speckles have faded and it looks like we have ended up with 2 males and 1 female.

We've not decided on a name for the pale quail yet. He's a bit more timid than the other two we currently have Waylon, Rose and Scaredy-Quail. It's better to have a high female:male radio so we are going to collect some more females soon.
