I feel like a total newbie where chickens are concerned even though I raised them for a few years 25 years ago. That time I didn't read a thing about them, did what seemed right, and must have had beginners luck for all were healthy.
This time I've read up on raising chickens -- starting months before I even ordered them -- and I seem to be second guessing myself as to what to do. Love this site!
Right or wrong, here's what I've done with my coop. I use lights on a timer to keep with summery hours so the coop is lit after the sun sets. I have another light - a red one - that comes on for about 1/4 hour before and after the regular light goes off. That way the flock isn't in total darkness at roosting time.
Aside: The grand-babies closed the coop AND the play yard today. No one could get in to lay and when I went out to tuck them in and lock the door after dark, they were all patiently? standing outside in front of their glass door staring in at the warm, lighted coop in total dismay. I think I detected a 'tisk, tisk' of disgust at my carelessness as they sidled past in to bed.
