Been reading all about heatlamps for the winter season, but I've got a question I haven't found the answer to yet.. I've got 8 hens ( 4 Comets, 2 Leghorns and 2 Black sex-links) in a 6x6x6 draft-free coop..If the temp really drops here in Connecticut and I use a lamp just to take the chill off and give them some extra light, is it better to come on at dusk and run for a few hours or turn on just before dawn for a little while ? or the heck with the lamp altogether ? I know I sure can't sleep with a light on in the room not sure how it affects hens though... Thoughts ?? Thanks !!
