Is it possible to have a sickness free flock..the reason I ask this is because I bought 16 bantam chicks from the local feed store and 11 of the 16 have died and the five remaining seem healthy but I am leary that they are because of the mass of mortality in the flock. The symptoms they (the ones that have died) were sneezing and when they breathed something made a pop every breath(thinking air sac/ chronic resp. or are they the same)..I am just beyond getting chicks just to watch them die and should I be buying them from a hatchery instead of the local feed store and what guarantee do I have that I wont get the same thing from the hatcheries
