Hens don’t lay in the rain

[z3lda3]

Let me rephrase, my hens don’t lay when it’s raining. I’ve got about 12 hens laying, some everyday some every other day. But when it rain, especially when it’s raining for days, I’ll be lucky to get 3 eggs. They’ve got access to the coop from the chicken yard/run. Nothing changes except it’s raining. The coop is dry, well ventilated. Anyone else notice this with their chickens? Or are my hens just really picky??
