I have 4 cortinix quail and keep them in a 6 by 6ft pen i think they have more then eneogh room but they always seem bored and are pecking at the sides of the pen (which makes me feel like I'm bring cruel keeping them) they have a mud bath and have plenty of grass, they've got tunnels, hides and I often give treats, there don't like being handled but there really tame and don't flinch at ask when I come in they even walk over my feet. I thought it could be becuase they are stressed but I can't see what their being stressed by. I would appreciate some ideas of what to do (they don't do it all the time about once a day) do u think it's becuase of the cockeral
