Welcome to BYC!

Here you can try find the correct forum and ask your question. Mods will move it to a more appropriate forum if needed.
Here, you'll usually get an answer that is from someone that is experienced or knowledgable of what you're asking. Some things may have lots of different replies, but nobody is attacking anyone. If that gets done here, they'll be warned or suspended.
But in most of those FB poultry forums, I've seen people's replies attacked because they didn't align with them and seen people attack the OP calling them basic idiots because they didn't know something. They are brutal on Facebook. I use FB poultry groups to sell chicks is all. You still cannot sell animals there. You just post a picture of your chicks/chickens, and tell folks to message you if interested. That's it.
It is also not up to the groups about this. I tried posting macaw parrot tail feathers in the Marketplace and FB deleted it telling me to read the rules. I appealed, twice, explaining they naturally fall out and I save them for others who make Native American headdresses or crafts out of them. They still didn't allow it.
