lambing season

The Sheep Shape Shire has been a busy place of late! New lambs, bottle babies, sadness, the meat rabbit startup, bee hive setup, high winds (again) and the chickens get a summer cottage! Whew! If it gets any busier I will have to give up sleep entirely! Though most of these things happen...

What signs will we see if there is a second lamb to be born? And how soon can we expect a twin to be born after the first lamb has been delivered? This is our first lambing season so we're not sure what to expect or to look for. Thanks in advance!
