Quail suddenly stopped laying!

[WhFarms23]

Hi all, I raise jumbo brown coturnix quail and the past two days there have been little to no eggs! This is starkly different from what I’m used to getting around 60 a day. They have adequate lighting, food, water, and there are no visible signs of aggression amongst them. None are molting and all have enough pen space to feel comfortable. It has been 90 degrees here for the past week other than that nothing has changed. Any thoughts or ideas? Please let me know. Thanks

I'm guessing that a predator has been hanging around.
