Opened a box of what I thought was just litter in the barn, wasn't expecting something to fly out! Didn't catch a glimpse of what it was. Robin? I've left it all alone, please tell me it'll come back.
Probably Robin. Quite a few of the small garden birds eggs are very similar in colouring. https://voice.gardenbird.co.uk/bird-egg-identifier/
Update.....4 of the 5 robins were born, all survived and flew the nest yesterday, still around the gaden tho, sussing out their own little territories. Ain't nature brilliant.
