Hello, welcome to quail! I recently got into quail myself. I had a similar issue with my quail, they took what felt like forever to start laying. A few things to consider:
- What are you feeding them? Quail require higher protein, and I've also seen that some won't start laying without enough calcium.
- What season is it where you are? A lot of quail will take longer to mature and lay during fall/winter - some of them won't mature or lay until spring unless you use supplemental light.
- What is their environment? Quail will stop laying if they're stressed, so if your roo is violent, or if there's predators coming by and scaring them, they might not lay. If you've changed their environment recently, that might also do it - I've found it takes at least a week or two for them to start laying again (or start laying, period, I guess).
- I've found that my celadons (blue egg laying quail) took longer to mature and lay. I've heard that's not always the case, though.
So - it can be normal, but it'll help for you to post pictures of their enclosure, what you're feeding them, etc.
