However, when asked if they've ever seen it happen then the answer is never. One or two I've spoken two have seen newborn lambs with their eyes gone but did not see how/what happened.
> I'm not saying it does not happen but I doubt very much whether it happens as much as we/farmers think it does..

> As for crows gaining access to the stomach cavity? I'm not sure. I've worked in areas where their are large populations of ravens (Shetlands) and it was obvious that any dead sheep/lamb was soon reduced to bones. I've never noticed this in areas where there are only crows.
> As for there being 'too many' crows. Well thats a matter of opinion really.
I've seen the crows stood over still living newborn lambs whilst their mother runs back and forth trying to work out which of her twins to protect. It does happen and it's on the increase around here as the population rises. The worrying thing is that last year it happened in the sheds for the first time. We're seeing a huge increase in the corvid population around here year after year, I'm not one for shooting everything in sight but it needs dealing with.
