Hi chicken experts... 1.If I was out of town and my eggs were not collected for 2 days will they still be good? (About 75 degrees here during the last couple days...50's at night) 2.Is there a "test" you can do to see if they are good? I thought I read something about floating an egg once. 3.If I have a broody hen, does that ruin the egg if she sat on it all day? I know I don't want them to sit on them, but does it actually make them bad if they sit on them for the day?
