I'm far from perfect with biosecurity within my own flock, and do forget sometimes to pay close attention to going from 1 pen to another on my own property. BUT... While I was out of town for 3 months and my bf was caring for my flock, hatching , & brooding.... I never even thought to explain the importance of it between the flock & the brooder. Since, my brooder has still never been empty, & we r getting deaths that appear to be from Cocci!! I have my last set in there now, & have had to start treating them. We have of course emptied, cleaned, scrubbed with bleach, let air dry for hours, but still its affecting my babies. No problems with any of my older birds, except a new pullet that hasn't been here long, just babies. After I've finished brooding this group, and the brooder has been empty for sometime, will it go awa, or "die" out? My incy is off, but I have ordered more eggs. :/ OOPS! I can brood the next set elsewhere, but I do not want to have to deal with this forever in my big brooder. Is there some way to fix this problem, other than burning my brooder? It wasn't cheap. Lol
