May I ask why you don't want to reply to comments? Conversations in the comments increase the likelihood that more people will see your post. I reply to almost every comment, even just to say thank you or sometimes I post a GIF. If it's something I don't necessarily want to answer via FB (example - no, this dog cannot go to a home with cats because he thinks they are snack food) I will just craft a general reply that keeps things positive and redirect. Example: Great question, Sally! Rocky prefers dogs and people to cats; he would not want to live in a home with a feline. We would love for you to come by our shelter and learn about other dogs who may fit with your family.
^^ I have some drafted answers to FAQs and go over them with my intern. We don't cut and paste but since we get asked similar questions often, it speeds things up.
If you have a volunteer checking messages, I would use "Saved Replies." Take the Top 10 FAQs you get via messenger and create a reply. Then the volunteer can automatically send what you've approved each time. It also helps them understand your expectations for when you reply to a comment.
