7 mo old hens laid one egg each and stopped laying! Help!

I have a cuckoo maran and an EE that laid one egg each three weeks ago, and haven't laid one since! They're 7 months old. The weather has been in the 85-100 range could that be why? They're confined to a large area, and I've searched everywhere in their run with no eggs found anywhere! Darn chickens, I've waited so long! Haha! Anyone know if this is normal?

I have read that heat can suppress egg laying. It could be due to that and the fact that they may be getting their plumbing sorted out also,as new layers. It might just be case of patience (no chicken keepers strong point)
