hi, i have 7 girls ranging from 10 week to 25 weeks. On the very day i was complaining that we were never going to get an egg as none of them were laying, i went to the coop and found an egg. Well it was like christmas as we were sooo excited. These next 3 days days though..... Nothing!! Gertie, who we think laid the egg keeps going into the nest box at around 1.30pm for about an hour, then comes out singing the egg sond as if she thinks she has laid an egg but all we find when we get there is the rubber egg i keep in there to encourage them. Could it possible that she thinks it was actually her that laid that rubber egg? lol.
