We lamb entirely outdoors. We have SBF x lleyn. All selected for easy lambing. I try to keep really good records; I used to think I'd remember, now I write everything down. The first and most important round is at first light, then 3-4 hourly through the day with the last as late as one person can bear knowing she is getting up at first light. If ewe drops lambs into rain and gale bring them in, warm them up let them out next day or as soon as its sunny. I can't catch lambs once they are over 24 hours old so iodine navels at birth then tag and tail and ball band at 24 hours. I can't get near the ewes so spray their number on their side at heptavac booster time. If a lamb gets stuck catch the ewe, get the dog, parents, neighbours, husband and make it as quick and stress free as I can. This year I want a flock sized catching pen to aid stress free catching. I overfed some ewes before lambing so 2 singles got stuck and needed help. I won't do that again. I'll scan them this year and only feed the twins.
Good luck with your lambing. Hope that helps.
