Im not the best person to answer all those questions you have alot haha, but ok to check for them you can run your hand under her belly push and let her run threw your fingers, and if you feel bumps kinda like golf balls right in a row. As for it being safe for her to breed, i dont think thats really true, she needs to be at the proper weight and age. And yes if they are not fertilized they are reabsorbed but i think if she us underweight she can become i think its called eggbound. Im sure others will chime in here
