I've been considering buying a couple of cockerels or young roosters and having them shipped. What are the pros/cons of this. Do the birds suffer from much stress? Are they in good health at arrival? If the are quarantined 30 days (even with NPIP certification) is my flock really safe? How far away do they have to be kept to avoid air contact (different building but adjoining runs)? I know it's overnight mail but still... I wondered what has been buyer experience. I'd really appreciate hearing from an experienced shipping receiver.
