Alan built a creep the first year we had lambs, but we rapidly outgrew its approximately 12 square feet size. Last year I used the long side of the creep in front of the door to the smaller stall. That worked great, but we lambed nearly a month later and it never got too cold at night necessitating the doors needing to be closed. This year we have had some frigid nights in the teens with the winds blowing right in the doors. We needed to come up with a creep plan that would allow the doors to be closed and still let the lambs come and go in the creep.
