I may be onto something with my girls, they don't all like to use perches so they sleep in the nest boxes that i always have to clean out! I use hay and have to dump the whole clump out because there is frozen poopy! I do this every day replacing the hay. I ran out so i'm using wood chips except for 1 box still has hay! THEY KEEP THIS ONE CLEAN! This is where i find ALL my eggs every day and i haven't needed to do so much maintenance! I average 2 a day right now...I know....i made it seem like All my eggs are abundant! However, both eggs EVERY day!
