Hello. I am new to the forum. I have a few that I am raising as egg layers. 5 hens. 3 roosters, one goose. I plan to get rid of at least one rooster. I have raise all these from baby chicks. All just shy of a year old. All hens are laying, but none were sitting. So i bought an incubator to try my hand for the first time. 7 hatched out of 16. Is that normal? What is a good surface to place the eggs on on the incubator to hold them upright? Can I use an old egg carton? I bought the incubator with no fan. Would addition of a fan help hatching ratio? The babies are 2 days old now and seem to be doing well. I plan to load up the incubator and do another batch, before it gets really cold. Thanks for your time.
