I have fun thinking about natural light probably because I live far enuf north that I see so little of it during the Winter and so much of it thru the Summer. Two months ago, there was only about 8 hours of daylight - we have already gained more than 90 minutes. That's quite a turn around and it improves my mood, enormously
.
Chickens also respond strongly to light. In their original home, they only lived about as far north as April there in Florida. Some wild chickens actually live south of the equator by a few degrees so the chicken's "biological clock" is set to almost equal daylight and darkness hours.
April, your chickens must be fairly comfortable with the seasonal changes. If they were to cross the Georgia line - everything would change!! No, not really but that's kind of "foreign country" for a chicken
.
By the time they got up to where I am near 49° north latitude, chickens must be saying to themselves, "What the heck!!"
We can't leave them on the roost for 16 hours out of 24 - I just don't
see how that can be justified. Any farther north and with less Winter daylight I'd be practically suicidal . . .
. . . and,
look I don't even want to think about the Seattle/Puget Sound area
. It has been
theorized that the sun is actually above the horizon at times there during the Winter months. It's just that no one has actually seen it
.
Whole corn? I've seen chickens have some trouble
forcing it down. I'm not sure if I can say that I've ever seen them
choke on it. One additional reason to mill corn is all the muscle work the gizzard has to go thru to grind whole grain. It increases the energy requirements of the critters.
