I have five young pullets in one coop/run as follows. Bobbi, who is an 18 week old Light Sussex. Fuzzy and Ugg who are 16 week old Pekin Bantams. Fleur who is a 16 week old Bresse. Dotty who is a 15 week old Silver Spangled Hamburg. Today I found a small egg in the coop, about bantam egg sized, I'm very surprised as the hens are so young. The egg on the left is from my 2 yr old Lohman Brown, Daphne. who lives in a separate coop/run.
