Mystery egg please help solve myster

[Merrymouse]

So my hubby come in the house with a pretty big egg. He found it on our front walkway. That's where the mystery comes in. My chickens are not free ranging. Also this egg is big! And more round than my chicken eggs. Could it be a turkey egg? Maybe my dogs found it in the woods and left it on our brick walkway? Not sure but it's a lot heavier than my chicken eggs and more round. Any ideas who may have laid this egg and how the heck would it come to be on my front walkway?? It's the one in the middle. The other two are my chicken eggs

Haha no idea, but if my dog found an egg she would have ate it

I think it was my retriever. She has a soft mouth. My setter would have eaten it straight away

My hound picks then up really gentle, but takes then to the porch and will repeatedly drop it till they break... I have to make sure my to collect eggs right way when I let the chickens out to free range as the dog walks right into the coop to collect eggs for herself
