My chicks are too little to measure them and work this backwards. We are building their coop now and want to hang the feeder and waterer under the poop board /counter which goes under their roost. I am trying to figure out how high the poop boards need to be to allow adequate space below for the feeders. This may be a dumb question because I know the feeders will vary in size etc. but I'm hoping someone can give me an approximate height? The chicks are Wyandottes. Lots of height in the coop but I also don't know if you can get your roosts too high for the birds to like it. This is my first batch of chickens!
