Katie is right, there is no fiscal
profit in rising bummers. That's why the farmers around here won't bother to bottle
feed a lamb. Another thing she is right on about is the set of lungs on a lamb. They can holler for days when force weaned. That's why I graft mine to the flock as own as possible, while they are real young. They live out with the flock and just come to me for the bottle. But I had to make a set up where the lamb can be separate from the flock for its bottle because the adults that had been bottle raised as babies also try to horn in on the action.
I usually only have one or two lambs on the bottle at a time, so I can handle them no problem. At one time I had 5 and I got mobbed! I had to modify my pen to accommodate five lambs in order to prevent the chaos and from being climbed on.
I never carry a lamb around, sit in the ground with one, and never ever let it climb into my lap. What they learn as babies the carry for the rest of their lives. It may be cute at 15 lbs and dangerous at 150 lbs.
Raising a bummer can be fun, but it also can be expensive, time consuming, tedious, and a pain in the neck.
