I was given a rooster in July so I had a black hen that came up missing about 3 weeks ago. I found where she was laying so I fed and watered here there. I had a couple others that did the same for a few weeks but produced nothing so I figured she would be the same. Today I found her roaming around in the barn with 4 lil chicks. Needless to say, it was a heart-pounding few minutes to trying to get them snatched up into safety before the cats found them. Now I haven't a clue what to do. They are in a large dog crate with food and water in the barn, mommy is keeping them warm but our temps are 50's and 40's at night, soon to be even colder. I don't know if she will be able to keep them warm enough or if they will be able to get out during the day to roam around. It very well could be 50's, 40's and even 30's during the day within the month. Any suggestions would be very helpful! I have never had to raise chicks in the fall. Should I put a divider in the large coop with the rest of the hens and keep heat on them? Bring them inside without momma? I really don't want to take them from her. Thanks in advance!
