Why do people use a raddle/marker?
Because they have no faith in the fertility of their stock?
They just want confirmation that ''something is happening''?
Because ''it's the thing to do?''
I'm not sure it's at all necessary in most situations
If you have a decent-sized flock, I agree, raddling not essential (and I've not done it for the last 10+ years).
But if your numbers are tiny, as mine now are, it's helpful to have a good idea when anyone might lamb. Otherwise one feels obliged to stay close at home all day every day for the whole 3 weeks or whatever, when most days, nothing happens all day long....
We're tupping 7 this year, and we're using raddle for the first time. I'm hoping I'll feel able to go out and about a bit more at lambing time next year.
