Well to start off, I have been raising chickens for almost one year. Bought my first chickens from ATWOODS and TSC. Then I got a few from a local Market and a BYC friend and now I have hatched over 50 eggs myself. Many for the local 4H, my sisters, friends. But a lot I raise myself. I have had a few come down with Black fowl pox, which of course disappeared. I had a few with coryza (IMO) that were put down and I know a friend that one of hers had cocci. With that said, as I read about all the diseases out there and how they are spread, i.e. some can travel a mile in the breeze, or you can bring it home from the state fair, I worry do my chicken really stand a chance? Here are a few things I do: INSIDE THE COOP I do put new birds at the other side of the property for up to 2 weeks. I do clean out the coops from poop and wood shavings twice a month. Then I spray down 100% of everything inside the coop with a bleach/water solution and re-wipe and scrub. Then I spray down with oxine. After that airs out and dries I spray poultry protector then I lay fresh wood chips and respray poultry protector. Then I air out the coop for hours before I let them come back in. (Chip/fumes) In between changing the shavings monthly I add DE to the chips to remove smell or moisture and some pests (I hope) and YES sometimes when the chickens are locked outside in the runs, I sneak in and spray LYSOL everywhere..... I mean everywhere. I close the doors and windows for 30 minutes and then I open it all up to air out. OUTSIDE IN THE RUN Once a week I rake inside the coop to get take "stuff" out that gathers in the coop and try to scrap the top of the dirt out too. Once or twice a month, when the chicken are locked inside the coop and cannot come into the run, I take the food and water dispenses out and then I spray the entire run, doors, wire roosts and DIRT down with 1/2 bleach/1/2 water solution. To include outside the run, where I walk and can transfer poop from walking in and out. I let that sit all night. THE FOOD AND WATER DISPENSERS Since my dispensers are 3, 5, and 10 gals I only water every other day in the winter and once or twice a day in the summer. My largest food dispenser is 7 pounds but I only put in 1/2 that. I also like to throw a small amount on the ground (which I worry about, but my Grandmother always did.) The food dispensers are plastic and I like to hose them off once a week and spray with a bleach/water solution, then rinse really well once a week. I have both plastic and metal type water dispensers. I do the same for them as the food dispensers. But they ALWAYS need SCRUBBED. In the water dispenser I like to put the appropriate amount of Apple Cider Vinegar in the to help the chickens as well as keep the slime off the inside of the containers. I know they say it is not good for the metal cans but so far I cannot tell a real difference. They look fine. Every once in a while after scrubbing them out I will run then through the dishwasher. CHICKENS I do in the summer use the poultry protector and luke warm water and give them a dip for 1 minute ( they love it once they are in it LOL) I also put down a little poultry powder in the bedding and lightly dust the chickens with it to prevent mites etc. Once a month or more I go in at night and lightly mist the air with the appropriate mixed oxine for they chickens to inhale. BUT THIS is the hard part. I am sure the chicks I bought at TSC and ATWOODS were not vaccinated as well as my new chicks for Maraks, Fowl Pox, New Castle, or anything else out there that we can vaccinate them for. I know there is a lot of meds out there to treat some of the diseases chickens can catch but I would like to try and PREVENT them from getting them. Now On they same line as prevention. How do you go to a County or State Fair and not worry you are bring something home to your chickens. And goodness forbid you put your prize chicken into the show and have to leave it the 3-4 days. I know those chicken have to prove the have been tested but that's only for a few diseases. So, what do you use to boost your chickens' immune system during show? Is it possible? BIO SECURITY AT MY HOME OR WHEN I VISIT OTHER CHICKENS At home I have 2 pair of chicken work shoes.....plastic crocks and plastic rubber boots. After each wear I rinse outside the chicken run, walk up to the house and (THAT's RIGHT you guessed it LOL) I spray 1/4 bleach to 3/4 water bottle on the shoes or boots. Let dry in the garage. If I go to someone else's house, I went out and bought another pair of crocks (Dollar General kind) for his house only. When I return They get hosed/sprayed and dried and put away. My cloths go into the laundry. I do not wear the same cloths from his house and then walk to my coops. Hands get washed. When I babysat his chickens I did the same. It was crazy for a week changing clothes three times a day. But I have a pile of JUST work clothes. I am sure I have forgotten something. Now I know there are A LOT of you guys that don't worry or do any of this stuff and your chickens are fine but I have hear around here as well as read on BYC, there is a problem. I have a lot of chickens and I cannot afford to let one sick chicken wipe out all of them. So I ask, What do you do as far as BIO SECURITY? What do I do that will not work/ What am I doing right? What should I be doing? Please let keep this nice, everyone has an opinion and I will truly appreciate all of them.
