We built two movable tractors for our meat birds and of course they made a mess everywhere they went. Well, my question is, if they had cocci and if I let my laying hens out to free range could they get sick from the meat birds cocci even though they have been gone for a few days and the temperature outside has dropped significantly. Could the cold weather kill the cocci if they had it? I am just a little nervous to let my reg chickens out to free range now. What do you think? Thanks.
