I use the same feeders (I like the blue, haven't seen that one! ) I use these while they are little and I can still stand for them to be in the house.
I moved my current batch (30) to the barn yesterday. I picked up a cool feeder. It is one of the lont red ones, but intsead of feed holes, it's open but with a lont bar running the length for support. A trough I guess. But what I thought is cool, is that the bar spins so the little brats can't perch on it and poop in the feed trough!
I Have never limited food, what is the purpose?
