Biosecurity was so drilled into us in high school ag classes and in my animal science classes in college. I feel like horse ppl don’t take it as seriously as would those working with other farm animals. I know much of it is hard, if not impossible, in a boarding facility.
I get the hairy eyeball for standard protocols. I quarantined my (pet) goat, who went to the fair, before she went back with her senior pal, etc. I warn ppl with backyard flocks to be careful without much success.
If you are considering this at all, you are leaps and bounds ahead of many. Some of the stuff can be elaborate to keep up with depending on the situation. Do the best you can. It isn’t too hard to leave “town” shoes by your front door when you come home and rubber boots by the back door. Wash your hands and if you have been in direct contact, change clothes. Extension always has lots of stuff on best practices. USDA and others have really been pushing biosecurity for backyard flocks, woth good reason, so there is a lot out good info out there.
Bird stuff is scary bc it seems so easy to transmit. Also be careful w pet birds. Good luck with the fluffs
