Has anyone had their sheep licking the walls of the their stall? We just got some new sheep and I'm keeping them in a stall for a couple days to acclimate and facilitate bonding. They're happily eating the hay, the corn and soybean mixed feed and even treats of oranges. Issue is, they don't seem to be drinking, but I've caught them licking the walls. What's up? @ of them are 2 months and one is 4 months.
