I am getting a bit worried that our standard 120 cm high arks, with curved corrugated iron tops, are not going to be big enough for our large Saddleback sow who is due to farrow in a month. She is 96 cm tall, but with the floor inside the ark, the overall height is about 116 cm with the doorway cut out right to the top. This gives just 10 cm clear height, but only in the middle due to the curving roof. The floor area of the arks is quite large 8' x 8' (2.4 x 2.4 metres), but I am wondering if she will be able to make use of this if she can't lie down anywhere except the very centre. Has anyone else had to resort to providing larger/taller arks for large sows, or can they manage regardless? Her current house is in the woods and unmoveable, and was purposely built to accommodate several mature sows - 120 cm high throughout the 8' x 8' area, but we cannot transport this back to the farrowing paddocks. Would appreciate advice - Tamsaddle
