Our laying ladies suddenly stopped laying

[ChicFil- A]

I was wondering if anyone knew reasons why our two laying hens would suddenly stop laying. It has been hot (low/mid 90's everyday) so I'm wondering if that may affect things? They seem healthy otherwise. We also realized one of our chickens was a rooster in the past couple of weeks so there have probably been some power shifts/light stress. We've been able to keep them cool with regularly changing out their water, lots of shade, and lots of cold treats, so I don't think they're overheating but it seemed to be such a coincidence that they stopped laying in the dead of summer (we got them as chicks last summer, so this is their first summer outside). Any ideas or advice to get the girls laying again? Thanks!

Sounds like the roo might be upsetting the coop, especially if they are young, coming of age… hormones play a large part of chicken behavior, or actually they may be going into molt, end of summer is molt season … good luck
