After a few weeks in the chicken tractor (see http://www.luckypennyacres.org/2016/06/26/baby-chicks-venture-outside/), the baby chicks were old enough to merge into the main flock. To help the integration process, we put the chicken tractor inside the main field where the main flock spends most of its time so all of the chickens could see and get used to the cochins before we merged them together.
We first introduced them into the main coop late in the evening when it was already after sunset and all of the chickens were roosting. Chickens are mostly asleep / zoned out while roosting so the older chickens didn’t make a big fuss and we were able to place the young chicks on the roost bars without any issues.
The chicks were also mostly asleep at the time, but the next morning they took the opportunity to explore the coop.
