Thanks for all the responses so far!
I didn't know about the timing for the bile test so that was great info for me. Reading up on some of these tests is different then practical knowledge which is extremely appreciated!
I also read an older post on breeders on YT who were discussing OFA. That was insiteful as well.
It's really invaluable for me to be able to get some knowledgeable info, so a big thanks to everyone posting
