Just because she is a proven breeder does not mean that she is ready.

She may very well be, but in the pictures she looks far too small.

Say a 1600g female is bred and lays 6 eggs, each weighing 100g...
That brings the female down to 1000g + all the weight she has lost during the breeding season which would equate to... possibly 900g.

Now if that female started eating and by the time cooling happens again is up to 1420g, would that (in your opinion) make her "all good"?

She would be too small.
