once again I am not sure where this question belongs. WE have been getting some eggs in the nests in the hen house. However I had Bill go check the horse shed (18 x20) cause a bunch of the hens came out of there today and after eating went back out to it. He brought in 31 eggs. Now since I only have 10 chickens (and as of today, only 9 could be found) Ii imagine they have been there for a while. I don't know which ones are new and which should be thrown away. I remember there used to be a test about putting an egg in water and if it floated or sank. But I can't remember which of the results meant bad and which meant good.
