I second the Blue Kote t can be bought at amazo.
Blue Kote will discourage the hens from picking at her.
Chickens love something to do and as stated, is the hen house big enough for the amount of chickens inhabiting it?
All of your birds need some help here, the whole flock need some WET MASH PROBIOTIC RECIPE..
Here is my recipe and it does work. the picked hen has some E-Colie wrong with her system and gut. In order to grow back her feathers.
WET MASH PROBIOTIC RECIPE
natural probiotic recipe is this:
THIS IS FOR ONE CHICKEN
IF FEEDING MORE CHICKENS MULTIPLY THE RECIPE TIMES AMT OF CHICKENS TREATED.
3 tbsp of dry crumbles
1 tsp of dry flax seed meal (kind for humns).
4 tbsp of milk, sweet, sour, or buttermilk or a mixture of all or some
1 tbsp of yoguart of non flavored yoguart ( no artificial sweetmer)
mix good
AFTER PUTTING VIT'S IN 1-1000 mg of Vit E( cut end of capsule and squeeze into wet mash)
1 Vit B Complex tablet crushed, 1 Selenium tablet crushed, put in wet mash.
PUT 1 TBSP OF APPLE SAUCE on op of THE WET MASH PROBIOTIC.
NOW THE IMPORTANT INGRIEDIENT FOR EACH CHICKen FED
for each chicken use 3 tbsp of mixture and 1-1000 mg of Vit E(cu end off casle and pou into wet ash)
,Vit B complex crushed, 1 Selenium tablet crushed
and feed each chicken
3 tBsp full of the wet mash probiotic and what they will clean up in 20-30 minutes
then clean wet feeders and restock dry crumbles
do this twice a day for a week
then quit the Vit E, Vit B complex, and Selenium, make just the wet mash probiotic
then once a week for life
All the while after medicating the birds use ACV unpasturzed kind. Braggs or Heinz ACV.
do not use ACV with medication
2 tbsp of apple cider vinegar per gallon of the chicken water so their gut flora wil be regulated
they should have this at least 3-5 days a week
then three days a week after they are over the sickness.
the vit's are necessary to clean up the damaged gut problem
ALSO AFTER THE MEDICATION IS DONE FEED THIS AGAIN as time listed
