Thanks, everyone. My mom's boss gave her a cage that was sitting in his warehouse and my mom offered it to me. The cage is 9' long by 2' deep by 3' tall and it is on 3' or 4' tall legs. I live in the high desert in California and it gets into the 100s for a little in the summer and it gets cold enough to have snow for a few days in the winter. What I was thinking about doing to the cage was making 1/3 of it into a wood box with a heat source and putting a roof on the rest of it. I thought of rigging up misters for the summer to cool them off. I am really hoping this will work because my lovebirds came from a aviary then went to a very stressful home in a tiny cage and not really interacted with before coming to me. I have had them for a over a year and even though they are a little better they are still very stressed being around people. I plan on building a 12'x4'x7' cage with the last 4' being a enclosed area with heat but I can't do that yet. The only predators would be Coyotes, owls, hawks, foxes and one stray cat. The cat does not go near where the birds would be going because of my mom's dogs and it has not messed with my Pigeons anyways. The Coyotes have never come into our yard and I don't think they would mess with the Lovebirds even if they did. The hawks stay away since there is a family of ravens who lives in the next yard over and they attack the hawks plus the roof on the cage would keep the hawks from seeing the lovebirds from above. The owls could be a problem but they have never messed with my Pigeons and the lovebirds would hopefully sleep in the enclosed part of the cage. The stray cat does not come near where the birds would be because it is afraid of my mom's dogs. We did have a fox try to get into our chicken pen with the Roosters but I don't think foxes would bother with the Lovebirds since they are up off the ground and my mom's dogs would alert us if it did try. Does that seem workable?
