Currently I have three female and two male Corturnix. They live happily with one large male rabbit. My thought is to get the rabbit a spayed female girlfriend for company because rabbit are social creatures. The rabbits would help to keep the birds warm in wintertime. A pair of giant, flightless pigeons could incubate quail eggs. For housing I have a dog igloo on the ground and a raised rabbit hutch modified with two nest/huddle boxes and a perch. The rabbit hutch has a wire floor that I covered with plexiglass because I don't think pigeons would want a wire floor. Ground in the aviary is gravel. Is this a crazy setup or a good one for pets with benefits? http://cdn.backyardchickens.com/7/75/751c9eeb_2012Mayrabbithutchchickencoop2.jpeg (I don't have chickens anymore and the wire on the bottom of the raised hutch is removable.) http://cdn.backyardchickens.com/6/66/66229b79_2012critterrunfinished.jpeg The run still has plastic deer fencing on the top, but the wire hardware cloth now goes to the top because the rabbit sits on his hutch and chews through it. The wood is all painted now, too. I wonder about feeding. Quail need high protein. The pigeons will eat mostly whole grains (12-15% protein) which, if large enough, the quail might not touch. All of the critters may eat alfalfa hay safely. I suppose the rabbits and pigeons may not do well on the higher protein quail food and so free-feeding might not be ideal and so mealtimes 2x per day are a better idea.
