Well I spoke with Mark from Freedom Cages today. Very nice man and very informative. I wanted a custom cage tailored to my dimensions but after realizing that the cost is astronomical, I decided on one of their model cages. I'm getting the Wekiwa model (
Samsula). Mark seems to think it'll be large enough for a harlequin. I'm very excited because it does seem like a very high quality cage. Unfortunately, it won't arrive for a few weeks. He told me that a shipment just left China yesterday and it takes approximately 20 days to arrive in the U.S. then it has to go through customs before it is delivered to me (about 5 days later). I think my bird will be ready before then and i'll be in a little pickle (I'll have the bird but won't have a cage yet--hopefully the breeder will hold him a little longer or I may have to buy a very cheap temporary cage).
