My chicks (8 weeks) will be spending their fifth night in their new coop tonight, and I'm surprised how easy the transition was. They had access to their run during the day while we finished up the coop, but would come back into their big box at night. From the first day we let them walk up their ramp and peek inside, they have been in love with their new home. They have gone each night into their coop as the sun started to go down without us having to push them in. The first night they slept in a pile in the corner, but the next night started roosting on the waist-high roost.. I expected to have to lock them in for a few days so they would know it was home, and I expected them to cry to come back in the house, but that hasn't been the case and I'm so relieved. It has to just be the instinct in them??
