Hen with possible water belly

[Lil Brown Nugget]

I have (2) 3yr old Rocks that one is walking with legs wide apart, paste butt, not too interested in food, she keeps moving her rear end like she is pushing, fluffed feathers, and her belly is soft and mushy like water belly. Her poop has been thick green and white but yesterday the white looked weird now this morning she pooped and I’m not sure what this is I posted both pictures from yesterday and this morning. Also she will not perch she sleeps on floor and today I noticed she is like moving tail feathers and rocking. What is wrong? Seems like symptoms for several things and sone of nothing. Thanks in advance.
Oh yes and the second Rock she is laying almost white eggs instead of brown. Some are hard sides with soft ends or some are just soft. They have free range oysters shell. The other four hens seem fine and laying fine. Just the Rocks are acting weird.

 

[Eggcessive]

Hello again. What is the stringy material in the left picture? Is that some sort of bedding or food/noodles? Is the hen with the dark green poop eating much? It looks like a lot of bile in her stool. I haven’t seen so much white urates like that. It looks like cottage cheese. The 3 year old rock sounds like she has a reproductive disorder in her oviduct, perhaps salpingitis. I saw egg shell problems after my hens had infectious bronchitis. She may also have water belly from the reproductive issue or liver problems. She sounds pretty ill. Do you have any antibiotics in case she would respond? Amoxicillin or enrofloxacin are the most used ones for reproductive disorders. I would try to rule out worms, or go ahead and worm her with Valbazen 1/2 ml orally once and again in 10 days, or Safeguard Liquid Goat wormer 1.5 ml orally for 5 days. You could take some droppings in a ziploc bag to your vet if they are willing to do a fecal float. Is she eating? How is her crop emptying?
