Slow egg production

[Chicken lover 4]

Hello, I have 3 chickens of mine that are all almost 2 years old. They have all stopped egg production. Ruby, a Rhode Island Red, has stopped late last year and has been pooping white runny poop every night. Thor, a blue wheaten ameracauna has stopped over the summer. Pary, a light brahma, stopped early last summer, and seems to have a swollen vent. It has been a bit cold, at 35°F every morning where I live. We have also mixed our flock with another flock of 4, but I seem fine together. They also have a worm problem, but we are taking care of them now. I hope you guys can help figure out what is wrong and how to fix it, because I'm stumped.

Very possible when the worm problem is corrected, your hens will get back into production. They have been off duty way too long to consider the egg stoppage as due to regular slowdowns such as molt.
WISHING YOU BEST.
