Depends on when she last laid eggs. Most proven breeders are put on the market shortly after laying a clutch and this time of the year is when many clutches are laid. You should see a lot of big girls but you can almost guarantee she laid this year. Also keep in mind some girls may take a season or two off. Ask the breeder when she last laid, breed her after a proper QT and she may very well go for you around the same time next year. I picked up a proven girl this past Jan and she had laid eggs the October before then. She started locking in May and should be ovulating any day now which would put her right on schedule for laying this October.
