7 month old - Stopped laying?

[RoseCityClucks]

Hey y'all,

I have 4 backyard chickens: 2 EE, 1 Barred Rock, and 1 Australorp. The two EE's started laying at 5 months exactly and they have laid an egg a day very consistantly only missing 1-2 days in the past 2 months. My Australorp is 7 months and just started laying this month, everything is going well there. My problem hen is my Barred Rock. She laid her first egg at 5 months, she has laid 2 eggs and then she stopped. It has now been 6 weeks and no eggs from her. She is not moulting and I have not changed food or anything that would cause her stress. My flock was dewormed and they do not have any mites. Why would three of my hens be laying well, but one would stop laying? Any ideas on how to start getting her to lay again?

I have had pullets start laying and then stop for a while, but not 6 weeks. Could she be laying anywhere else?

Nope, I've scoured the chicken yard and unless she is burying them quite deep, I don't believe she is laying. She appears to be in excellent health too. I just don't know what would cause her to quite laying. She has access to oyster shells. They get their fare share of daily snacks like broccoli, spinach, meal worms, occasional fruit. I'm really stumped, I've went through lots of posts regarding this matter and couldn't find any advise that fit my situation.

What does her comb/wattles look like? Are they bright red or pale and pink? Have you checked around her vent for lice?

Here is a picture of her today. She is very healthy, no lice or mites seen. They are also offered DE baths and its spread throughout their enclosure. She acts very normal and like I said its been 6 weeks since her last egg, so I presume its not egg bound.

She looks like she should be laying with a comb that bright and red.

That's whats baffling me! She is so healthy and big. Only got two beautiful eggs from her and now, nothing.
