Hen has become SATAN chick and stopped laying eggs!

[Cetawin]

If they are 8+ months old they should all be laying. What breed are they? Are you sure they are not hiding eggs somewhere? That is really odd and a very late age to just start laying.

The hens are OEG/Wheaton mix.

We got them for free and did not know what breed they were at the time.

I know they cannot be hiding the eggs anywhere because they are kept in a 10 x 10 enclosed coop. (we have too many predators to allow them to free range)

Seriously thinking of just getting some RIR and Barred Ply. Rock.
Can I put them in the same coop with the ones I have now? Can I still keep the OEG Roo with them?
