Please rethink the, summer off, statement. Your female is doing what I call a run out. That is, shes going to lay many clutches. If you support her, she will be fine. She may do this for a year or two. Then return to a more normal, one or two clutches a year.
Heres the problem. If you feed here, heck even if you don't, she will still lay eggs. Only the effect will be far worse on her. If you do not allow a male, she will merely lay infertile eggs, which again is much harder on her. At times they will form eggs only to absorb them and become infected. Man thats a bad thing.
My advice is, saddle up cowboy, and go for the ride. Keep her healthy by doing what you have been and all things will be fine. With the possible exception of you have far to many baby monitors to deal with. Again congrats and ride that horse cowboy. FR
