Hello and Welcome to the group! What breeds are you raising?
Keep their area as dry as possible. Don't bother with heat lamps.
Carolyn - We have 4 RIR and 1 Ameraucana {who has yet to lay at 28 weeks;disappointed}
Welcome!
Make sure your birds have a nice dry, draft free place to hang out if they want. Other than that, mine go out in the rain as long as it isn't pouring. They got extra hay during the ice storm we had. They love alfalfa leaves and the stems help with walking. The first time it snows each year, they all freak. "OMG! The white stuff! It burns!" Then they get over it and don't care.
Hinotori - Thanks, glad to hear that at least some are okay with getting wet.
I guess as far as the rain goes as long as they can get inside if they want to be dry then they are good. We are looking at putting some sand down this coming week so we do not need to move the heavy coop around this winter. We have come across many design flaws.
Have you guys seen a drop in eggs yet? We have a light on a timer and still getting the same amount of eggs each day. Would we have seen a change by now if they where going to start protesting because of the days getting darker earlier by now?
