Forget producing lambs, this lot will be laying eggs soon.
They get a ration of sheep nuts daily but can still find room to snack on layers' pellets and poultry corn. One of the ewes inside the pen is on her knees so she can push her head through the pop-hole the better to reach the food.
Had I wanted to get two ewes into a confined space it would probably have taken me all morning and many curses. The hen house door was open for, hmm.....probably all of 45 seconds and they were in. Water was syphoned up, food located and food snarfed. Done and dusted.
