I've seen breeders have a good big female plop out a nice size clutch one year and the next time they breed, her clutch size grows by one more egg.
I just wonder has anybody gone from 4 eggs one season to the next time around just having double that or close to double in clutch size? Does age or weight play a part?
(Example)
Past: 1500 grams 3 1/2 years of age; clutch size 6...
Present: 2200 5 years old; clutch size 9
Is it possible or pretty much what you got first breeding you can't expect much next breeding?
