Sheep with no milk

Hi!

I'm raising sheep and goats and I really try to understand that one.

My husband found a newborn lamb yesterday morning left my its mother.  We have several pregnant ewes so we called them and could identify the right one because she had a string hanging.  
We put both of them in a jug but we had no idea when the baby was born.  The lamb is very active and was chasing us when we found it.. running. However, the ewe is avoiding the lamb.  We watched for a while and we decided to try to hold the lamb so it can suck on.  No success.  

We tried to milk the ewe by hand... no milk... no bag, nothing.  It's dry like an old lady  

We are bottle feeding the lamb.  It's small, 3 pounds.  Normally they are much bigger.  

Does anyone knows what this could be?  

The baby is so small I don'T even know how much milk to feed.  This is so weird.

Some ewes won't bag up until they lamb. I've not experienced this with mine but I do hear about it from others.

Newborn lambs need to consume 10% of body weight in colostrum. so 4.8oz if I did the math right.

Being smaller than usual and no milk I would think possible premature birth. However if the lamb is acting normal than it can't have been all that early. How big are your lambs usually? I would keep a close eye on them.

Is this a first time mom? Sometimes first timers get freaked out by the birthing and associate 'that thing' with the trauma of birthing. This can be compounded if they have a full udder and nursing is painful initially being over-full. Obviously that isn't an issue with this one.

What is the breed?
