I would agree Lee. Have feeders that have used the small pens. Now most ,that individually feed, have a 10 by 10, with feed and water set up. Lambs either live in the pen 24/7 and get exercise via Walker , track, and road , or are run in common pen ,with exercise area over night, and penned up during day.
If I was to feed,it would be that way.
Use lambing jugs for feeding pens during, and run together at night.
Part of ME, says I never want my lambs trained to " Back up". And backing them out of a feeding pen, twice a day, is certainly doing just that.
Just another bad habit, that now needs corrected. The less that lamb ,has to learn, the easier it's is for me. I want to teach him to walk ahead and drive up and ahead.
I do not want him learning to walk backwards and then every time I ask him to drive, he backs up from pressure on his head.Which I have conveniently "trained" him to do,by backing him out of a feeding pen.
Call me crazy.
