Turkey feeder

[silarajc]

I currently have chickens that I want to make a feeder like this for, but will be getting turkey poults in June. I am wanting to make a feeder like this for the turkeys:

I've seen it recommended to use 4" elbows instead of the normally used 3" if roosters will be feeding, and smaller elbows for chicks. I was wondering if the 4" would be big enough for my Narrangasett turkeys when they are grown? I've never had a turkey, so I have no concrete idea of their behavior or size.

I'm also getting ducklings and guineas...Would this idea work for them as well? Would the 4" elbow be enough for them?

4" should be enough for turkeys yes. That feeder may not work as well for ducks as they scoop food more than peck and also may clog the feeder as often get the feed wet.
