Safety of using infertile eggs as fish food

[Gerg]

We feed our aquaculture fish (silver perch) boiled chicken eggs as the main protein component of their diet.
Each month we incubate about 50 eggs and usually have a reasonable number of these turn out to be infertile.

What I am wondering is, after candling at about 7 days in the incubator, would it be safe to do a long boil of the infertile eggs and then feed it to the fish? Fish are cold blooded so I am thinking that well boiled eggs that are removed after 7 days are unlikely to carry any particularly nasty pathogens?

Does anyone have any insights on this subject?

All raw eggs should be assumed to carry bacteria. As long as the eggs are thoroughly cooked to remove bacteria, I believe they'd be safe.

As long as the raw eggs do not stink like rotten eggs I would not hesitate.

If bacteria gets inside those eggs the bacteria will multiply and the egg will stink. You do not want anything to do with those. Toss those, carefully. Whether the eggs are fertile or infertile has nothing to do with it. If bacteria gets inside a fertile developing egg they will multiple, kill the embryo, and stink. If bacteria does not get inside an infertile egg that egg remains as safe as any other egg.

Whether at 1 or 2 weeks, you can sniff the clears and boil them up for your fish as long as they don't smell like rotten eggs when you sniff them through the shell.

I read once you can use them for baking (I never would). So I would think with them hard boiled they should be fine.
