During WWII my grandfather kept hens (about 2000) for egg production. As the the
darker nights started, say from Sept onwards he would put Tilly lamps (a
pressurised kerosene lamp with a very bright light) into their nightime quarters to
keep the light for the same hours as in summer. This maintained egg production at
the same level throughout the year. This was a wartime neccessity.
Evolution has pruduced animals that thrive in the wild and natural state including
seasonal changes. We can't expect to change to artificial conditions without a
downside, The hens produced more eggs annually but for fewer years.
For many years in the UK ferrets were nearly all only kept (outdoors - natural light)
for rabbit hunting and control and I think you would find it very rare that any of
them ever lost their fur due adrenal problems.
My home is ferret proof - my heart is not.
[Moderator's Note; technically this is off topic, and affects might depend on lighting
type as well as airborne pollution since hydrocarbon lamps are connected to
induced pulmonary limitations in a wide range of animals, and because lamps/bulbs
very quite a bit in terms of brightness, wavelengths, etc. Anyway, this will be the
last chicken post in this discussion, since this one doesn't have anything to do with
ferret health, but it was interesting and Smartgroups is repaired, so in case it
interests others...]
