It is to bad that you had all those tree trunks removed. You could have used them to make a raised foundation for the sheep shelters, filled that with dirt and sand, and maybe it would have been high enough to avoid flooding.Sheep have shelter from the rain, but water runs in the shelters and/or the ground gets so saturated that it’s just wet slop.
A semi-permanent solution would be to put in french drains but it is a lot of work and would still require you to raise the shelters. Dig a trench around the sheep shelters and put in perforated pipes, cover with rock, and hopefully the rain will drain away from the shelters. Adding a deep french drain pit (abut 2-3' diameter x 4' deep filled with rock) at one corner and sloping the perforated pipes to drain to it will work even better. But again it is a lot of work and there is cost involved. It might work better to use the tractor to slope your night pen and put the shelters on the top of the slope.
