Biosecurity, STRICT biosecurity. Keep all visitors out of the hen house, family,friends..... EVERYBODY since you do not know where their shoes have been. Disinfect your shoes EVERYTIME you go in the hen house. Don't wear the shoes you wear in the hen house any where but in the hen house.
Stay away from chicken auctions, chicken fairs, chicken swaps.
And pray.
