It is tough to control outdoors with physical or chemical measures of the pathogens transmitted through wild animals.

How to prevent a wild bird from flying over our layers? however, if we can use an exhaustive vaccination protocol during breeding, immunizing our animals well, so that when they come into contact with the outside, they will be immunologically well prepared and do not suffer from any immunosuppressive disease that can facilitate infection and spread of other pathogens.
