The day old chicks were already out of the house and in a crate in the barn.
They quickly outgrew the crate and needed some more space. At around age 6 to 7 weeks, we moved them into the movable chicken tractor so they could experience full outdoor weather for the first time and better hone their foraging skills before merging with the main flock.
Here is a video of the chicks their first day in the chicken tractor:
The chicken tractor is moved every couple of days to a new spot to avoid dead spots in the pasture from too much foraging and digging. After a couple of weeks in the chicken tractor, the chicks were finally ready to join the main flock.
