Egg bound cornish rock?

[Harold the Hen]

I found my hen in a nesting box this morning all limp with her eyes closed. She wasn't reacting to the food. She looked dehydrated so the first thing I did was give her some water. She wouldn't drink so I simply trickled it onto her beak. Her eyes would open for a little while, but they always went back shut. I pulled her out and she stood up and stumbled a bit. I brought her inside and checked her vent which I think might be slightly prolapsed. I was worried she might be egg bound since she hadn't really been eating and she lays pretty large eggs, so I put her in a tub of warm water. She's passing a little bit of waste, but it's not solid. I gave her some more water. Right now she's breathing a bit better and her face has a bit more color, but she's still pretty limp. She is responsive when I pet her back or massage her abdomen, but otherwise she's sleeping. she's a bit stronger than she was when I found her in the nesting box. I think it is worth mentioning that I found one of my cornish rock roosters dead two days ago , and one of my other roosters is having some sort of respiratory problems. I already ordered some things for parasites and vitamin supplements to help treat my rooster. I also put corid in their water a few days ago. All my chickens are around 10 months old now.

I don't know what else to do, I really don't want to lose another chicken so soon, but she might simply be close to her expiration date, she is a cornish rock chicken ):

Edit: She passed. It looked like the egg was coming out, but then she started to convulse violently. She stopped breathing, she vomited, and then she died.

Sorry for the loss. Cornish X sadly do have an early expiration date.
