Order Only: Private message to Fred Weasley and George Weasley

Gents, could you pass along a message to your Transfiguration teacher for me? It's from Charlie. (Obviously, make sure you're totally private first, please. It'd be a good chance for you to practise your Muffliato.)

Tell him that Charlie says that whatever those blokes who are visiting the Reserve are doing to his dragons around the solstices, for the wards, it's making them [the dragons, that is] more and more tetchy, earlier and earlier, each time. Charlie says he still hasn't had any luck figuring out what's going on there.

Sending this along in case it means something to him.
