Is there an Android phone app for Facebook Group Chat?

[tinkerbell]

So I have an Android phone. I also am a member of a Facebook group (just a bunch of moms).

We are in our Facebook Group chatroom all throughout the day. I want access to THAT chatroom - the one associated with our group FB page. But I want that access via an Android phone app. I don't want to make a NEW chatroom... (I have seen a few apps that do that, but that is not what I want).

I know I can log into facebook using the internet browser on my phone and use "full site" mode, but it doesn't let me scroll the chat, and the chat box doens't even show up on the page half the time.

I can't seem to find an app that has this feature. Help?
