This spring I'm totally reformatting my coop to make it more efficient and easier to clean. However, with the plans which I have now, I only have roughly 40" by 30" (ground surface, basically unlimited height) of space to put roosts for, at maximum, nine chickens. So, here are my questions: (1) Is it best to make the roosts all one height, or will they still use the roosts if they are made at different heights? (2) I know my best bet is probably the ladder design, but how well does this work? Do the hens bother using the lower 'rungs' on the ladder, or just fight over the top one? (3) The type of roosts I was thinking of using would probably give roughly 65 to 70 inches of roosting space, is this enough for nine hens? And nestboxes... (1) I have the option of either two or four nestboxes. Is two enough for nine hens, or should I go out of my way to make it four? (2) Will hens still lay in a nestbox if sunlight can shine into it during a few hours of the day, or do they only lay in dark spaces? Sorry for such a long post. Thanks for any opinions/advice!
