Hi Everyone Someone just told me that you can tell if eggs are fertile or not before putting them in the incubatoris to candle them, and if there is no air pocket that they are infertile. I did a search on this site and elsewhere and couldn't find this information, so I am going to all of you. My roosters obviously have favorite hens and I hate to waste what would be eating eggs if they are infertile, not to mention that I could be using that space in the incubator for other breeds fertile eggs. Thank you!!
