I was kept awake most of the night by baaing and got up this morning to a Gotland with twins, these ewes are in a group of six together. I then noticed another baby near her and thought, oh she's had triplets! I went into the stable and saw another baby, and started to think, quads???

as all the babies were round one ewe.
But thought another ewe must have lambed so looked around and sure enough one of my most friendly ewes had a messy bum. However she didn't seem interested in any of the babies, whereas the other ewe was! I deduced that two of the lambs with white head markings must have come from her as she also has white markings, but she would only accept one of them and violently butted the other one away, who went back to the ewe who let it suckle. The friendly ewe seems to have become very flighty and nervous and wouldn't let me near her, so I decided to put her in a stable with her two lambs away from the others. I left them alone for a while but when I looked later she was still rejecting one lamb and being quite violent with it, and this lamb also didn't seem to want to go near her.
I had to go out so put the little lamb back in with the other ewe, who immediately licked it and let it suckle. It seems for some reason the ewe, a first timer, has accepted one lamb but not the other and the other ewe who has lambed before is very maternal and welcomed this little lamb into her brood.
Im not sure what to do now as the lamb will have drunk from the other ewe making it even more likely to be rejected

. I gave the single lamb some powdered colostrum as I haven't seen it suckle yet and will check tomorrow. I don't want the other ewe to be burdened with three although she's happy to feed them all, so it looks like I will have to be assisting with the milk.
Is it common for ewes to become nervous after birthing? If anything my others have become more mellow!
