ok i have 12 hens that are just starting to lay. i had 1 nest box and when i got 6 eggs in one day i added 2 more. unfortunately i went to check for eggs a few minutes ago and had 3 hens trying to share the same nest box. the first box is a large milk create about 18"x24"x12" so it could accommodate 2 in a pinch if they would stay at the ends. they all explored the other 2 boxed which are half bushel baskets all on the same shelf as the create. all of them are bolted down and have the same pine straw nesting material. why arn't they using the other nest boxed instead of crowding each other in the same box.
