It isn't really that cold here, maybe about 30 at night, but I've lost three chickens (two babies and full grown bantam wyandotte) to the temps! Pretty sure that's it at least, as the bodies were unmarked and stiff, covered in frost. I'll be moving all the babies inside all day and all the adult bantams inside at night, but what do I do for the larger birds? Their coop is very open to all the weather, and every time I make shelters and fill them with hay, the birds kick it out! One bird is also in a molt, and I'm worried about her a lot because she looks so naked! Running a heater isn't an option. There is a shed I could put them in, but the cages are very small for them to be staying in for the week until the warmth comes back. Maybe put them all in at night? How cramped can a couple of chickens (a HUGE EE roo, an Australorp, and a Leghorn) be and not start pecking each other?
