You have to take the milk from cows, but chickens are supposed to voluntary gift you with eggs even though they may do so in their own good time. You shouldn't look a gift horse in the mouth. Chickens also like a settled routine, Swedish sauna baths, spa treatments, and Roman massages, are too much like trying to take the milk from a cow and they interrupt a hen's daily routine besides stressing her.
Every hen has days when she doesn't lay. Normally a hen begins laying in the late morning hours and she lays a little later each day. Finally when it becomes too dark for a hen to lay she goes to roost and skips that day without laying. Then she resumes laying the next day, usually in the late morning hours just as before. Also some show and dual purpose breeds only lay 3 - 4 eggs per week even in the best of times.
You indicated the sex and age of your hen (1.5 year old female) but you didn't tell us what its breed and ultimately what is its disposition for laying lots of eggs. Is it possible that your hen want's to settle down and rear a family by setting? When a hen takes to her nest she stops laying entirely.
July and August are just around the corner and when the Dog Days of Summer begins is when the molt is due to start (and especially with "heritage" chicken breeds) when the molt starts is when egg laying goes right out the old window, often for 3 months or more..
The best of luck to you and to your hen.
