When to discard bad eggs?

I have a few eggs i'm pretty sure are clear, but i'm waiting until lockdown to toss them out, just incase. Don't want any stink bombs exploding all over my new chicks.

 

it is not too risky to let clear eggs stay.. if you have a cracked egg, those are the bombs.. If you smell something bad, locate it and toss it..

with dark eggs that you cannot candle well, you can wait until after day 15 and then float it in warm water.. If the embryo wiggles, the egg will bob in the water.. real easy to see..

 

I've had loads of infertile eggs, loads of embryos that have died in the first ten days, and loads of fully formed chickss that have died in the shell without pipping. But I've never had a bad egg yet. Duds aren't dangerous to leave in, and from what I've read, the smell of a truly bad egg is unmissable. If you're new to candling and you don't smell anything bad, I'd say leave them ALL in. You don't want to chuck out a viable egg by mistake...

Quote:Very interesting! We have a few under a broody right now. She started with 9 and we are down to 5. So far we've been correct on infertile/bad eggs. We cracked them once we felt really sure they were not developing. They've all just been white & yolk. I admit though, I'm a little nervous each time. We're learning though, so I won't be too hard on myself if we make a mistake. I thought I had read with my Brinsea info that the most reliable way to know is to weigh the eggs. Fertile eggs will get lighter.
