Two mornings ago I heard my chickens up and making noise at 4:30 am! We have one especially loud Black Sex Link who makes a lot of noise many mornings, usually when another chicken is in her favorite nesting box. (Strangely though she has pretty much quit laying eggs over the last month or so, even though the other 5 are all laying, but that's it's own question I guess). This morning my daughter woke at 4 am and told me the chickens were awake - I looked out that window and 4 out of six were down in their run. By 5:30 the noisy one was making a fuss and sure enough another chicken was already in the nesting box. I had no idea they were up that early. What time do your chickens start getting up? I always thought it was with the sun, but there really isn't daylight at 4 am here.
