I keep a light (200 Watt bulbs) on my horse from 5PM-11PM and 5AM-7AM. I live in Alabama and the weather is still warm. Why is his winter coat coming in thick like last year?
Why would the light not help? And what could be wrong with the lights? He's not sick... all of the horses are starting to grow their winter coats. He had a summer coat, and his winter one is just now growing in, just like last year when I did not have a light on him. He has been in the pasture all day this summer, and is 10 years old.
