Hi everyone! We are building a chicken coop and I need to get some ideas on how high the roosts need to be off the floor and also what size board to use...also do I need some sort of ramp going up to the roosts? Also i was wondering about what size nest boxes to make and also how far up do they need to go? We are building a 12x12x8 coop.....we have 25 chickens that will be in there when finished. They are standard breeds such as Barred Rocks, RIR, Turkens, Wyandottes, Jersey giant, Buff Orps, Golden comets, etc. Any suggestions and advice would be greatly appreciated! thanks!
