I started out with 2 of these cages from Tractor Supply 3 weeks ago and my quail quickly out grew them. They didn't seem happy and made no sounds.
Then I bit the bullet and built a proper pen. Now they dus bathe, bark ,sing, chirp and chase each other around and seem real happy.

Hi. I bought some quail from these guys in Ceres. They are adults. Very tame and they wait for me to get home like puppies.
