i too have been doing much research on the pros and cons of flight. here is my ? i am more concerned about the german shepard/ shiba inu mixed dog that i have. harley (my dog) is two years of age and very quick. i dont have the grey as of yet. (still doing research) and i am not wanting to kennel the dog, or cage the bird for long periods of time. how long does it take a grey to learn flight? also, is this a major disadvantage to adopting a five year old bird?
found this on the web, thought i could post it here. lots of interesting stuff on the pros and cons to clipping flight wings. as of yet i am not sure of my opinion.
