Mmmm. 2 years, 14 ewes and I havnt seen one being born yet I do 2 hourly walks around the field in daylight hours and I'm sure they wait till I've gone to pop em out
They do.
No kidding.
I have some rules of thumb about intervening or not.
Up until there are toes I am fairly patient. It can be up to 4 hours after water bag before anything to see - although I probably pop a clean well-lubed finger in just to check it isn't a tail or a nose with no toes after 1 or 2 hours, or if the ewe seems distressed or looking likely to get worn out.
Once I know I've a nose and two toes, then I just want to see steady progress.
No progress for say 20 minutes despite ewe working hard - explore and help. Not pull, just assist with steady pressure when she pushes. Sometimes it's a question of just easing the flesh of the vagina around a large head - just keep working it around with your finger, gently and well-lubricated. Some of our large commercial lambs, you need to just pull the legs forward so she can get the shoulders through.
Any serious resistance, I usually will then follow each leg up to make sure they're attached to the same pair of shoulders
.
No progress once the head and feet are out - I don't wait 20 minutes, I get straight in there with the assist. If it's got big shoulders or big hips it could stay stuck for a while, and potentially suffer or cause harm to any lambs waiting behind - and you won't do any harm at all just easing it along as she pushes once she's got the head and toes out. Again, sometimes straightening the legs can help the shoulders come through.
If she's scanned for triplets I want to see numbers 2 and 3 pretty quickly, especially if she's been a while getting no 1 out. If it's twins I am a bit more relaxed about giving her time to lick and mother no 1 before getting busy with no 2.
There are times I am more hands-on - for instance, a ewe going into labour late evening when we're busy in the full throes of lambing. Sorry but more will suffer if I don't get a good night's sleep, so I'll give her a wee while to get on with the job but if she doesn't then I will actively help. And pull no 2 out too because I won't go to bed until I'm sure both have suckled, and it can take a good 30 minutes before they're ready to try.
We lamb mainly outdoors but if the night is likely to be wet, and anyone looks imminent, especially if it's an inexperienced ewe, then she'll get brought in. If she's started before bedtime then she'll be lambed and the lambs suckled as above.
There may be the other odd ewe gets lambed when we're at our busiest - if for instance she has great big 'cow tits' and/or a big pendulous bag, it's likely the lambs will need some help getting latched on. If it fits in with routine checks to see her again later then she can be left to do it on her own, but if it's a choice between lamb her and get them suckling, or hope it all works out ok, then she may well get lambed.
