A lot of times with a question like when they will lay it is helpful to have ages in weeks as "6 months" can mean +/- 4ish weeks from one person's interpretation to the next and that 4 weeks can make quite a bit of difference in maturity of the bird.
Your little grey one is a pretty little Easter Egger pullet - they are often misrepresented as Ameraucanas. She will *probably* lay eggs in some shade of blue or green as they are mixed breeds using blue egg breeds as part of the equation, but the colorful eggs are not a guarantee - just so you are prepared for the possibility.
Can you get a clear side shot of your gold laced?
Really, neither the EE or GLW look like they are too terribly close to laying - things you'll see is growth and reddening of the comb and (at least for the GLW) wattles, performance of the submissive squat (if you reach down for them they bow and spread their wings slightly as though they are prepared to *receive* a rooster) - so you probably have another couple of weeks to wait still.
