I've had them moult early before although none yet this year - well apart from the geese. I'm having awful problems with crows so no eggs due to that but they are not subtle so you would have spotted them. Oh, and my ducks who traditionally have laid in the morning in the shed before being let out have taken to nesting in the thistles enabling the crows even easier access. None of which seems relevant to you! Hopefully if all your birds are moulting now, they'll be through it soon.
