when we farrowed in a stable, and had the creep too far from the sow, the piglets wouldnt use it. so we put the creep in the corner and the sows bed around the creep, this worked much better for us. the first week is the worst for crushing and i admit to spending alot of time in the stable day and night, and did sometimes have to get the sow up as she had sat on someone, or pull someone out just in time.
we only lost one piglet to crush and that was a gos in an outside pig ark.
