Dd's pony is at a DIY yard. We were away last week, and the owner's daughter looked after her. She lives out. Every evening the girl made up a feed, took pony out of the field (she's the only one in the field who gets a feed) and waited while she ate it (about 20 minutes- she's a slow eater) then put her back.
I said I'd pay but like an idiot, didn't make a proper arrangement, I've just texted her mum to ask how much I should give her and she has helpfully replied "whatever you think". And I have no idea at all. What do you think?
