I have three orphan lambs ages 5 weeks, 8 weeks and 10 weeks. They are all eating creep and grass and have access to water at all times. The two older ones are drinking a fair amount of water but the youngest won't touch it. I would like to wean him in a week or two but presumably I can't if he is not drinking water from a trough.
Is there anything that I can do to encourage him or do I just wait for him to work it out for himself?
