absolutely

I wondered the same thing when I was buying this and went out on a limb and bought it. I LOVE IT!! The side doors are too small for the typical parakeet nest boxes sold. It just won't fit in the door. You are right that it is built like a tank, and I did easily hang a nest box on the wires but inside the cage, just because the door is not the right size. I used a heavy duty zip tie, (pet shop's idea who breeds their own parakeets) and just hung it there by the whole on the top of the box. It was very secure, birds climbed all over it and slept on top of it, but decided not to breed. I then acquired another breeding pair, and just put the box on the floor of the cage...just set it there. The seemed to like this idea much better, and I screwed a small perch right in front of the opening of the box. This worked perfectly. The divider makes is very easy to just separate the breeding pair from the rest of the flock so they don't fight or bother the new parents and babies, but they are able to see, touch, and talk to each other very easily. Hope this helps....I see you posted this 7 months ago so maybe you already solved your problem.

Thank you for your inquiry. The cage itself weighs 33lbs.

Thank you for your question. The Hampton Breeding Cage System without the stand weighs approximately 31 lbs. This does not have an opening for a nest box.

Thank you for your question. The Hampton Breeding Cage System does not have nest box doors. At this time, we do not suggest placing a wooden nest box on the bars, as it may be to heavy. This cage can house Quaker and/or Conures.

No, this cage when assembled does not fold.

Thank you for your question. We reached out to the manufacturer and they provided this answer: Regarding our cages, Prevue Pet Products uses only the best baked on powder coating materials, for a superior and safe finish. All of our materials are tested both for durability and safety, and we adhere to the highest level of standards.

Thank you for your question. At this time we do not have any cages that would be appropriate for pigeon breeding.

Yes there are individual food doors for each of the feeder cups.

I'll answer your question one number at a time for easy clarification. The first number (18) is the width (left to right) of each cage compartment. If you pull the divider the new length is the 37.5 inches because there is additional space between the cages not accessible because of the divider. The second number (17) is the depth (front to back) of each cage. That does not change with or without the divider. The third number (16.75) is the height of each compartment. Don't forget there is a floor between the upper and lower levels. When you stack the cages the outside height becomes 34.5 but that is not usable space because of the paper tray, bottom grate and roof in between cages. Each inside section height is still 17 inches. So the single cage compartment is 18" wide, 17" deep and 16.75" high. Since you get 2 side by side if you pull the divider it is 37.5 " wide but still 17" deep and 16.75" high. If you order both cages stacked, the inside useable space does not change. What changes is the overall height of the entire system. The overall height becomes 61" (just over 5 feet ) which is 2 complete cage systems with the stand. The stand is the same depth and width as the cages. I hope this helps. This is a wonderful cage system and I have 4 cockatiels in mine. I have the 2 cage system (4 compartments) and stand.
