^This post has a photo attached. Two pullets have their heads in the picture. I am pretty sure those two pullets are NOT laying, because of how pale their combs still are.
Some pullets will start laying in the fall, while others wait until spring. Some start laying at 4 months old, others wait months beyond that point.
So I'm not sure whether you should be getting any eggs or not.

You can try checking their butts.
The cockerel will be a good example of a non-laying bird, so check him first for the experience. Notice that the vent is relatively small and puckered, and just below the vent you can feel the ends of two bones, close together.
Then start checking females. One who is laying will have a larger vent, especially wider, and it will look more moist and stretchy. The two ends of bones will be lower down and further apart. The changes are based on what is needed for an egg to actually come out.
Pullets will start showing these changes before they actually lay eggs. But if the pullets have vents and bones just like the cockerel, then nobody is laying or very close to laying.
