I'm looking for an answer before I post but either it's not here or (more likely) I'm not seeing it.  I have three pullets 9-12 weeks and I made a feeder following some pics.  It is awesome-the feed stays dry-it is easy to fill-etc.  But.  They won't stick their heads into the PVC pipe to get to the food.  I sprinkled some right up to it and even into the pipe and they peck all around and seem oblivious to the pipe opening that is 1/4" from their beaks.  The pipe is 2" round and almost at ground level.  Anyone else see this happen?  I could put a larger (3") pipe elbow in, but it looks quite large enough for them already - it seems like they can't connect the pipe with the food...this is going on 6 days.  maybe it takes longer?
