I know this has been discussed before, but I can't find it. If you are hatching eggs from your own hens, how long can you leave them sit before putting them in the incubator? Rather than put in 5 or 6 eggs at a time, Id like to put a whole batch in for one hatching, but Im not sure how long I can safely hold eggs before incubating them. This isnt shipped eggs, this is my own eggs. Thanks.
