This is our first year with a flock and DH and I had been debating about what to do in the winter. We are leaning towards not bothering to light the house for additional eggs but will use the heat bulb we used in the brooder when it gets cold enough outside. Is this enough heat for our flock? I was thinking of using it when it gets to the 30's. We live in Maryland so there will be plenty of cold days coming. At any rate here in Maryland we are on day 3 I think of cold rainy all day weather. My flock loves being in the rain and these past few days are no exception. Their run isn't covered so I have been letting them free range like usual for part of the day and I'm guessing they know they can always come under my open porch for cover. But what about a night time..especially when the flock is getting so wet. Should I bother with heat on these nights? I think it was in the 40's last night. I picked our birds since they are known to be hearty...RIR, NHR, a cochin, a sex link, and a wyandotte..so I'm hoping what I read is true and they can handle this. I'm also considering with winter coming to put a tarp over part of the run..might help a part stay dry if they choose to stay under it. Though I don't think they will. Anyhow I'm looking for any thoughts and advice. Thanks!
