I have sent pictures of my both quails, when you see then reply me , i will tell you which one male and which one female as my thought.
These look more like Japanese quail, one Tibetan coloured and one Rosetta. Neither can be visually sexed. Sometimes only the dominant male will crow. They take awhile to settle into new surroundings and can take up to 12 weeks to start laying. Any changes to their environment can stress them and stop them laying eggs. Just cleaning them out can make them skip a day! Hope that helps. And I hope you get some eggs soon!
