It is interesting what a diverse response these type of questions get..... I read the threads, and start worrying at my apparent slackness (sometimes....)
Since you invited lots of responses, however, in respect of the worming, and in view of resistance issues, our experience (admittedly limited and with a small flock) has been to move flock onto clean (ie nothing on for at least 4/5 weeks) field four weeks after lambing.... this means that the ewes move just AFTER the peak in their worm production....
We haven't wormed ewes or lambs for last two years, and do the fecs each September, on the lambs, just after weening...... vets have reported back that we don't need to worm...
Of course, now I've posted this we'll have a year or more of worming issues......
