Due to a serious attack issue of BO on an injured Wyandotte, I had to take my three 14 week old girls (2 Welsummers and an EE) and put them in with my older girls (1+yrs old) while the culprit was placed in Chicken Jail aka mini-coop that had formerly housed the babies within the coop. Now the youngsters have access to the Layena. Are they old enough to transition to Layena...I've always waited for that first egg before making the move before.
