They probably do just like the porch.
I wondered why Peggy Sue didn't grow much of an undercoat this year! I guess it's because she slept in the master bathroom every night while she was pregnant and spent the afternoon on the couch with me (we were both pregnant and uncomfortable, now we're both nursing and uncomfortable! ). She only went out to do "business" and have a mid afternoon graze so she didn't get cold enough.To much conditioned space will hinder their undercoat growth. I wouldnt even think of turning on a heater for them at temps above freezing. I know you just wanna give them the best possible treatment but without a proper undercoat, they will be worse off out in the cold.
Goats originated in Africa. It's hot in Africa. They don't need an air conditioner. It isn't hotter in Arkansas than it is in West Tennessee, where I am. A good shady spot will work just fine. If they do have to stay a a barn to get shade, a fan would be handy.SUrveyman, Yes I have an airconditioner. It gets really hot like 100 for a month or so in the summer so I have an airconditioner. I only put the heater on when it is really cold.
I did catch the snake that was living in the goat house. It ate all the mice and then I killed the snake. Hopefully they will go back into the house.
