iodine just the navel, if you do it by spray, it is more efficient use (ie less) No need to clean the lamb off - best not to or it will lose the smell and ewe might abandon it
We collect up the afterbirth, using the big red gloves / plastic bag, tie a not in it and it goes into the bin.
Leaving it around or in the muck heap will encourage fozes / rats / badgers etc
Ours lamb outside. It's the ones who have needed treatment or are thinking about rejecting their lambs that we bring in. Some first timers , if they have had a hard birthing or have twins, benefit from being inside, on their own, so they can bond and also easy to get hold of if there are any problems
They are pretty wonderful things and generally get on with it, however, feeding too much to late can cause problems with big heads and horn buds, as will crossing with texels types (dependant on what they are put onto of course) GOod luck and keep watching them
