That's too bad about the egg binding. I'm sorry for your loss.
One way to help prevent that ever happening again, should you
have any females, is to make sure they have plenty of calcium in
their diet, including a cuttle bone available at all times.
Males or females can use the calcium but it's especially critical
for the females. Low calcium is what causes the eggs to be too
soft for them to pass. You might try leaving the TV or radio on
for him for company when you are gone. But if you do get one,
even if it's from a breeder, quarantine is always the best way to
go. Good luck with whatever you decide.
