Have found 1 egg from my Polish where are the rest?

[RawDaddy]

Currently have 11 hens and 5 of them are Polish. The 4 oldest hens, they are not Polish but a mix of other breeds, are laying every day to every other day. The next 2 are my Polish sliver laced. They are definitely of egg laying age, in fact I stumbled across one egg while watering down the yard, it appeared in one of my raised beds. It was super small and very round. Here’s the problem, I have searched high and low for their eggs and have found nothing. We thought we had a problem early on with our 4 oldest hens because we couldn’t figure out why only one was laying eggs. Well only one was laying them in the nesting boxes. But then we found these after coming home from Vacation.
So then I found this I believe it’s a Polish egg? The small egg. Or do Polish lay eggs that are the same size and shape as all the other birds? And haven’t found another one like it.
Any suggestions?

How odd, that's an weird shape and size.
I thought Polish laced cream or white eggs.
Maybe one or two Polish are laying there, you'll have to keep an eye on that nest.

Those are not Polish eggs, Polish eggs are white. They look like beginner eggs from a pullet. What other breeds do you have in your flock and what are their ages?

Free range birds sometimes need to be 'trained'(or re-trained) to lay in the coop nests, especially new layers. Leaving them locked in the coop/run for a week or so can help 'home' them to lay in the coop nests. Fake eggs/golf balls in the nests can help 'show' them were to lay. They can be confined to coop and maybe run 24/7 for a few days to a week, provided you have adequate space and ventilation, or confine them at least until mid to late afternoon. You help them create a new habit and they will usually stick with it. ..at least for a good while, then repeat as necessary.
