They are in their run in the evening and by about 10pm it's time for bed when I ask them very nicely to go through their cat flap and into the shed - of course there is always one of them who thinks there's just the chance I'll leave them out for once (which I won't and never have) so he makes it very difficult. I end up poking them with a long stick (they have a long run with tarpaulin over it and a hidey house in the run) so it's very difficult to get them in. Any ideas how to make it easier?
