I have 1 chicken who started sleeping outside on the ramp. They have a coop and run and during the day we let them out to wander around the backyard. One of my Leg Horns started sleeping on the ramp... Before both my Leg Horns would sleep together in the door way and the other 3 would sleep inside on the roost. I figured they were keeping watch? One Leghorn went broody so she is always in the box and the other doesn't sleep in the door way but on the top of the ramp by the door. Is it normal? Should I be worried of her getting sick? She can't get eaten because its fully enclosed. I have 3 roosts and 5 chickens so I'm sure that is enough for them. This is my first time owning chickens and they are about 6 months old and all laying. One just went broody 2 days ago so I just learned how to break that. I saw something about putting a light on inside the coop for at night but will they sleep or just mess around all night? She seems to be fine, eating, drinking and her egg laying is the same. Maybe she just prefers to sleep outside?
