I am chomping at the bit to add to my flock. I am worried about AI. Would it be any safer to buy eggs than to buy chicks/grown birds or is the risk inherent no matter what age/stage of development the bird is in? Is it safer to buy from npip flocks or do they not test for AI? Would you recommend simply waiting until this AI scare blows over or simply quarantine any incoming birds? Any advice on disease prevention is much appreciated!
