I have two quail chicks being raised by two meat-chicken chicks. I started brooding them separately, then had them in the same brooder, but separated with a wire "fence" between the halves. Found the chicken chicks had vaulted the fence and were snoozing peacefully with the quail. Since then, the four chicks live together, and my one 'special needs' quail chick (not really sick, but delicate, much smaller than the other quil chick and it nearly failed to thrive) has done MUCH better since the introduction of the two chicken chicks. I put one of those elevated cookie sheets in the brooder, the type that has 3" legs on it, and wrapped the wires with an old dishtowel to give the quail space to get away from the bigger chicks if need be. I've been very happy with the way this has turned out for all of the chicks and less work for me. A shame that the chicken chicks will be processed so soon, they always have the NICEST personalities!
