Robin size eggs

[campclaus]

So I have about 11 assorted chickens over a year. Orphingtons, deleware, ee, American, austrolorps. They all lay pretty regularly. We also have 4 babies that are about 11 wks, maran and partridge penedesca. I have now for the first time ever collected 3 robin size eggs. Is it possible that its one of the babies laying?

No. 11 weeks is WAY too young.
One of your hens (or 3) are laying fart eggs. Just a mishap in the system, usually not an issue but if you keep seeing these then I'd suggest find out who's laying them and cull or take to vet, since that's not normal
