Hiya so after a little research ive realises breeding is not going to be as easy as I thought I was wondering if you could answer some questions to help me out. How long do you leave hens in a breeding pen to have best chance of fertilised eggs? How long will eggs be fertile after you have taken the hens out of the pen. I read eggs can be fertile for a month or longer if so do you just keep adding the eggs to the incubator over the whole month which means you could have a egg in the bator aged 17days old then add a new egg of a day old? Or do you just collect eggs to a certain number say 10 incubate them and disguard the other fertile eggs for the remainder of the month? Or do you keep 2 seperate incubators?. Id appreciate any help,many thanks.
