No, pufferfish will not lay non-fertile eggs. I have had multiple pufferfish for over 5 years and they haven't laid non-fertile eggs. Although she did mate with my other pufferfish and lay fertile eggs.
No but the age of the hen does?
Before birth.
Parrot eggs are either fertile when they are laid or they are not fertile when they are laid. They have to be fertile and properly incubated in order to hatch.
If they are round and plump. Infertile eggs also tend to be yellow. Even if the eggs are dented I would still put them in an incubator until they mold since they can still be fertile and produce perfectly healthy babies.
A woman is born with all the eggs she will have. No more will develop. If the woman is in good health and has a normal hormone balance and is having regular menstual cycles then she is still fertile but her eggs will not be as high quality as the eggs she has when she was younger.
no

As long as they have a fertile rooster around who is breeding with them, they should certainly lay fertile eggs, though golden sex links only very rarely get broody and sit on eggs themselves.
No
Fertile eggs
After mating.
