Thinking about maybe putting my most reliable ewes into the field to lamb outdoors but not too sure how a fully outdoors lambing system would work?
How do you catch the flighty wee things to jag and iodine them?
What if it snows?
What if torrential rain?
What if the mother isn't tending to the lamb properly and you can't really tell as they are all running around?
What if a predator gets a lamb?
As you can see I have quite a few concerns about it as I have always lambed outside and then brought animals in however this year thanks to the bloody bird flu going around the shed in the field are full of birds.
The way we do it:
We don't iodine or use antibiotic at birth as risk of infections is lower outside, but I catch to ear tag and castrate whenever I first see the lambs so no more than 12 hours old, as Hebridean lambs get up and running very quickly! If running, I use a crook to catch the lambs.
We have had snow a few times, and rain is very reliable at lambing time in Scotland! The lambs are so hardy that we only take in crosses for a night of born in snow to make sure they get a drink of milk in their bellies to keep them warm then back out, otherwise we've had multiple lambs born in the wet that do just fine.
If the mother isn't tending to the lamb, the lamb will look hunched or lie away from the others and you'll know there's a problem, but it's rare in native breed sheep if you let them get on with it, they're more likely to be nervous and potential to leave the lambs if you stand around watching them.
It is rare for predators to get them, the ewes are protective and the lambs are up and running in no time. We had two (ewe scanned twins) taken at birth last year, I found the ewe slightly cast on a slope and the afterbirth but no lambs, so a freak accident, she'd have easily seen off a predator if she could get to her feet!
My thinking is that there's either the risks of infections - pneumonia, watery mouth, joint ill, etc - if lambing indoors, or the risk of lambing difficulties or predators outside. With the hebs, I think the outdoor risks are lower than the indoor risks so that's the option we use, but it all depends on your facilities and experience and which situation you feel less risky for yourself.
Hope that helps
