Is it possible to have a sterile female? I have a het RAPTOR female that has been in with my male tremper since she started to ovulate in January. I've seen them do the deed several times, and she has never laid eggs. I know it isn't the male because he was put in with a different female for 2 days and she laid eggs Jan 15th and they are doing great. The female is a year and a half old and is 67 g. Should I wait another year to breed her or just leave the male in with her for a bit longer?
