Now how could you feed a sweet little dumbo off lol. Just kidding... Although I do admit when picking out feeders the dumbos are the last to get picked. Lol
To the OP, it's a pretty common thing for BP to go off feed. Actually I can pretty much say with confidence that if you have BPs at one point in there life they will go off feed. Follow the great advice given by the above member and she should be fine.
