I asked this recently because I went out to visit them. Very clean, lots of birds on display that appear to be well cared for. One of the owners personally spent about 45 min chatting with me, helping me explore and research various species I was interested in. For a price (I'm certainly willing to pay) they harness train your baby.
It did strike me as odd, however, that for as many as they have available, they don't seem to have room for what you would assume would be breeding pairs. I certainly didn't see any made me wonder if they were more a broker rather than breeder.
Is there a general consensus on whether brokers are to be avoided? I know I'd love to give them my business, based on prices, customer service, and variety of options, but if there are issues with brokers I'm open to hearing them.
