What exactly do you mean with "un-expected event" ?
Do you mean that he stopped eating? Or did something actually happen, and subsequently he stopped eating and is loosing weight ?
Many males stop eating while they breed, and loose a bit of weight, that in itself is not concerning.
BUT if something happened that compromised your males health and well being, and subsequently got him to stop eating, that is a different story. Did he regurge any meals ? Was there a lost of heat ? Health issue ? Stress of some sort ? In any such event, I would concentrate on getting him well and 100% , before letting him continue to breed. No clutch of eggs is worth burning through your adult animals.
In that case I would seek out another visible pied. However, you will not be able to quarantine your new animal and you will expose your females to him. Mites and disease can be passed on...
If you get another male, I would choose the breeder carefully and only buy from someone with STELLAR reviews. Not just on "what" or "how much" they produce, but reviews on their integrity and selling of healthy animals.
Kudos on valuing your animals health and well being.
