Welcome White Sky Take a look at my gallery and my website there are some release cages there. My husband made a heart shaped release cage with two doors in the front and we are just putting the finishing touches on two rectangular release cages to used for special events.We found building our own was the best way to go. We also have display only cages for our Frillbacks and Fantails.
Also join the white dove release group on this forum there are a few of us around the world.
Will post some pictures of the new cage over the next couple of days
