I must have missed where they said it would be a clinical practice business. I assumed they'd offer it like cat cafés where you can chill with the cats. Or like veteran's horse therapy programs where for free of charge, you go spend time decompressing with horses.
It is my opinion that it would be fun and lots of people would enjoy it. However, it's also my opinion that it would be a biosecurity risk not worth taking. I have horses. I still enjoy volunteering at a stable that does therapeutic riding for children with disabilities. Just because someone goes to "chicken" therapy doesn't mean they aren't around other birds.
