Here’s a tip to let you know when they are going to start laying. Hopefully you spend enough time with the girls to be able to easily touch them when you are in the run or coop. When they are about to start laying, if you touch them on their back, they will squat and put their wings out a little. All of mine did it and within a few days they were laying. It’s called Lordosis. Do a search on here for Squatting. There are some videos. Good luck. I was one a day, then two a day then five a day and on and on. At the point they started that, I went full layer pellets.
