We had bitterly cold weather last night; the thermometer read -5F this morning when I got up, which is close to the coldest I recall from this winter. Yesterday was +5, I believe.
Yet, despite the intense cold, the goat kid born two days ago continues to thrive. It helps that the lower portion of the barn has remained closed day and night, and I've been leaving the lights on 24 hours per day. The inside temperature was 26F when I went out this morning; it felt quite warm after walking across the driveway at -5F, but 26 degrees is still objectively very cold. Especially for a two day old baby animal.
The hardiness of these animals is remarkable. The kid had hunkered down in a cozy portion of the pen, next to Mom, and was just fine when she stood up to greet me.
