You really wouldn't believe how much easier this makes life. I just pop the bottles in the racks, hang them on the side of the hurdles, and stand and watch them drink. The most I have to do is nudge a lamb towards a spare teat if she's trying to barge in on another one. Of course I still have to wash the bottles and mix up the milk from the powder, but, honestly, that's nothing to having to feed each lamb one after the other.
Things are brightening up!
