I had an avian hen and really liked it but once. Compared it to the dsd I sold it and went with the dsd. Now with that said, the new avians are smaller than the originals and supposedly have a new paint scheme. The size and weight of the avians were some of the factors that helped me make the switch. I've seen some photos and video of the new avians and they look much better now. It might be a tougher decision for me today if I was still in the market. I love my DSDs though!!
