I'm so new to this, so I've never (gasp) even seen an actual bantam hen (only pics, that doesn't count). I really cannot fathoM the size. I have decided to gear my coop (4x4) toward a bantam only dwelling. I'm not sure how high (yet) to put my PVC feeders or PVC waterers. But let me back up: I'm using the 2x4 for the roost, but am curious if the actual poop board can be just 12" to do the job, or even less than that? General consensus for the bigger ladies indicates 14" on up.... Just trying to conserve room in the coop, but I also want the poop board to do it's job! Someone else has to have bantams only, right!?
