It was 3 above zero last night and one of my does had her babies. We have a hutch outside under a pine tree, 3/4 is wire cage and 1/4 an enclosed area with a "door" for her to come and go. At 27 days I put in LOTS of good hay in the enclosed area and on day 30 she started to pull her hair. Last night, day 31, she had her buns. I checked on them before I went to bed and she had them burrowed deep in the hay with fur under, over and around them....they were soooo toasty warm. All is well tonight, she has have lots of warm water today, warmer tonight about 15 above. I got her at a poultry auction this spring, she was @ 9 months then. She is large, grey -black coat. She was not bred before we got her and this is her forth litter for us!!!!!
