I agree with this so much! My coop is not heated either. I have heard it causes more problems than it helps. My 4 horses live in a 3 acre fenced in area with a run in shed (we have to hay year round). I do not blanket them. They grow gorgeous, nice thick winter coats! In fact, blanketing them can be very bad, because it flattens the hair and takes away it's ability to fluff up, which traps air and keeps them warm. They have done studies on how it is that horses feet and ears don't freeze. Their circulation to their feet and ears actually changes as needed. If the feet are too cold, the vessels open up more and allow more blood into the feet. However, nature also helps with that because horses have no muscles in their feet, only tendons and ligaments, which don't need much warmth to stay useful. A horses digestive system is "modified" so that eating roughage generates a lot of heat. So as long as a horse has enough hay to eat, and has been allowed to acclimate to the temps as it gets colder, they will stay warm. My chickens have shavings in their coop and when they perch on their roosts, they squat down and cover their feet. So far all my birds are rose combs. I understand that single combs can be an issue, but my sister has single comb birds and has never had any freeze.
I want my animals to be functional in nature as they are intended to be. I want my chickens to be broody and able to raise their own chicks. I think breeding that out of the birds is a terrible thing to do.
I have read that it is a bad thing to help a chicken hatch out of the egg. As hard as it would be not to help, if the chicken isn't strong enough to get itself out of its egg, should it really be used as a breeding chicken? Next thing you know, not only will birds not be able to brood their own chicks, we will breed such weak chicks we will have to help them all out of their eggs! Not a good thing.
I should be getting my first batch of Nankins before too long! I am so excited! Thank you Lund Poultry! And I have chicks on order from Mary Ann as well. Of course since it's so early in the season they will be indoors for longer than normal, but next winter, they will be outside in their coops for the winter. I want them as show birds, but I also want them to maintain their hardiness. I do not want to breed that out of them.
I will post pics when they get here!
