There are those that choose not to have their birds outside for many different reasons, we can't all live in the perfect spot to have outside aviaries.

It's been so many years that I had forgotten about this, but yes, we used to not only blanket our show horses in winter, but we added lights over each stall to lengthen the day and prevent the horses from developing that heavy winter coat. That is how most horse people are able to show those beautiful shiny coats on their horses at the stock shows in January and February.flywhoaman wrote: I raise horses and we find that if we add light in our (show) barns during the winter, the equine response is not to develop a heavy coat. Blanketing helps but the light guarantees this response.
Light is important. Not for vitamins but for emulation of the endemic habitat.
