I agree... Shipping a full grown bird seems like a recipie for disaster in MY opinion. That is assuming that you could even find a carrier that 'would' ship a full grown and live bird... Good luck trying to get insurance for THAT shipment/package... If the bird died on the return shipment the owner would be out a TON of money very quickly.
Hell, I would LOVE to take my dogs with me when I travel overseas but I know darn well that them riding in the cargo hold would FREAK them the heck out. (they are too big to ride in a carrier WITH me as per airline rules)
As for the people that think this may be 'cruel'... Give me a freakin break! How is this any worse than me deciding to eat the darn bird! Drives me nuts when those sort of people try to stick their noses in there and tell me what I can and can't do with MY animals. They are MY property thank you very much... If you don't like it move to europe or something - You should fit right in there with those people (people that gave up their 'rights' long ago). Most of these people that cry and whine the most about debarking dogs, tail cropping, and ear docking have NO FREAKIN PROBLEM if an owner wants to have their dog spayed or neutered... Most of the time they actually suggest that owners spay/neuter... How in the heck is trimming an ear or debarking a dog 'cruel' but it is 'ok' to cut their nuts off???
