At Lovebirds On The Common, I have over 250 Lovebirds, they do LOVE the Happy Hut. Unfortunately, threads come loose inside or outside and the birds get tangled in them. I have had one die from strangulation and two that have lost legs and toes. These were new Huts that were inspected by me. I have also had dozens of other incidents with the loose threads, but luckily found the birds in time to free them. I have removed all Happy Huts and put them in the trash. Probably well over $1,000.00 wasted. There is a much better brand on the market made of fleece. I can be contacted through my web site, www.aviary-amore.com
