I took the average of our 3 breeding seasons that we have completed and got just at 80%. We are not a big breeder but we have a small/med collection.

Our first year we had 1 female to breed and she laid 8 eggs, 4 of which hatched.

Our 2nd year we bred 8 females 7 laid and 38 of the 39 total eggs hatched the one that didn't hatch was a slug.

Last year our 3rd year we moved in the middle of breeding season and I think that through everyone off. We bred 30 females and only 11 laid. 4 eggs did not hatch (development ceased at some point during incubation) and 2 where slugs.

This year we are breeding 44 females and we shall see what happens. I am only expecting about 30 to lay but hoping for all 44 .
