My nine week old silkie lives in the coop with my big girls and his/her brooder mates. They've been in the coop for a few weeks and everybody else was roosting except for my silkie. I hadn't had time to build a ladder for him to get to the low roost. I went into the coop this morning and he was on the roost all by himself! I'm so proud, I knew he could do it if he just tried! Yay!
