I ordered a pullet surprise from Ideal, a dozen of them. They were shipped yesterday and should be here tomorrow(unless the mail lady didn't call and she has them in the car). So with 12 ordered how many extras could I expect? I have a small /medium brooder set up with momma naked neck waiting .I could, well should I rig up another brooder just in case? How many has everybody else getting and what breeds? They had a over hatch yesterday if it helps and they are going to south central Ky. Its only 60s/70s weather wise .
