Hiya Ive been incubating for a while now (few years) and was speaking to a breeder who is a young 73 yo. When I told him I had some 10 weekish pullets he made the comment " gee you started hatching early. I wouldnt its not a good idea" and when I asked him why his reply was "you'll find out the hard way" ???? no idea what he meant, he wouldnt elaborate. Had no issues to date. Im im australia (I know different country) but im seaching abroad for answers no one Ive spoken to here seems to know why other than heat being an issue in the incubation process (my bators are indoors and so are chicks for the first part of their lifes) Does anyone have any idea what this could mean?
