We also leave them in their pen until they are back on their feet properly. Both for welfare and practical reasons, I also think you potentially get problems with newly castrated boys getting left behind, which is distressing for ewe and lamb, and also with the numbers we have to get done, I don't have time to match up unnecessary muddles. I do 2 'putting out' runs a day, one after breakfast and one after lunch, usually each taking a couple of hours, generally the morning ones will have been ringed overnight and the afternoon ones in the morning after the previous batch have gone out, so they have had a good few hours, but if not, I ring and before I start putting out, then do runs/walks of girls only before putting out boys or boys as part of a pair.
