Other things to check pre-tupping include feet (you won't want to check them again before lambing), teeth (in older ewes a broken mouth will mean she may not be able to eat enough to support carrying lambs), udder ( no lumps or redness and inflamation, correct suspension) and that backsides are clean - that shouldn't be a problem for you. When checking the tup, check his feet (no footrot to pass onto yoru pasture, no lameness to distract him from his preformance), genitalia ie penis and scrotum (no signs of infection, discharge and that there are two evenly sized testicles present). Also check his general health - clear eyes, no signs of orf, no signs of footrot, and that he has been wormed - anything which could be passed on to your ewes.
Our ewes are wolfing into their hay up here. There is still grass but it has been well frosted so will not contain much nutrition, nor be very palatable. All the sheep are also eating every nettle they can find.
