I'm glad it helped. But
@aart 's post is right about whether the egg is good or not. I was thinking age, not bacteria. I once put all my eggs in warm water, planning to pull them right back out to wipe them and store them. Then something happened and I was distracted by a wounded hen. Long story short, the next morning, there were my eggs sitting in water in my garage. I threw them all away. And yes, they were all sitting on the bottom of the bucket. So float test or not, I didn't trust them even enough to feed to my chickens. Probably would have been okay to do that, but I wont feed them something I wouldn't eat myself. Well, except for their crumbles. I wouldn't eat that. And meal worms...wouldn't eat that either.
