my coop is not the largest, it has room for four chickens MAX!, but as of right now i only have two; so i still have room inside to put their water thingy, but im finding every morning it is full of wood chip and other things the girls decided to put in it durning the night. and im wanting to get another chicken so the upper put of the coop will be a bit full with three chickens and the water dish; do chickens need access to water during the night time hours? can i leave the door open and leave the water in the buttom part or the coop. It is a coop with an upper and lower section, top is completely closed off with wood panelling, with just a wee window, and the buttom is also closed off but with heavy-duty wire, so they will be safe from predetors either way. Can i leave the door wide open; its like leaving the door to their bedroom open not the front door of the house?
