Rattle breathing Hen that won't eat

[kaperi]

Hi there,
i'm asking for your help. One of my Creamlegbar girls (named Plume, which translates fro Feather in french) she stopped laying for a couple days before I noticed.
Then she seemed sick (wouldn't get out in the morning, etc) so I brought her inside. Noticed she wasn't eating or drinking, had swollen eyes and had rattle breathing (by that I mean she would make sounds and open her mouth looking up)
I started giving her water with a seringue. Then I did a 6 days penicillin treatment to see if it would help. Her eyes arent swollen anymore, I give her oatmeal in water in a seringue, but she did loose a lot of weight.
She can still stand on her feel and all. If you look quickly she seems ok but won't eat or drink..
So I give her everyday 3X a day seringes to keep her hydrated. Sometimes at the end of the serigue treatment she starts rattling again, like gasping for air.
I startedto give her diatomeous earth with the seringues so it can treat if there are parasites inside.. also did an external treatment too.
I don't have access to a vet, neither to medicacation for worms because I'm in canada.

I looked online for hours.. does anyone have any idea? I don't want to put her down, she does not seem like she's suffering but she clearly is not well.
I've had her inside for 8 days now. All my other girls outside are fine!

thanks in advance for your precious help.

It sounds like she could have a chronic respiratory disease. Tylosin, doxycycline, or oxytetracycline are very good medicines that may treat her disease. Penicillin is not usually effective for most respiratory diseases. I would mix a mash of water and chicken feed, with perhaps a little plain yogurt and scrambled egg to offer her. Tuna or salmon, or canned cat food are usually tempting. If she won’t eat or drink at all, I would attempt tube feeding her. You can use a length of aquarium air tbing with a 35 ml syringe, or get a proper feeding tube kit from your vet. Fluids are most important at first to get her hydrated. Here is some info on MG, a common respiratory disease:

Hi guys. UPDATE on PLUME'S HEALTH

She's still inside. i keep her in a room with low heat. it's been 2 weeks now. i stopped froce feeding her because she seems to have gained appetite but i'm not ready to put her back outside in the freezing weather because she did lose a lot of weight while she was sick.

I noticed today (right picture) that her comb is very very pale, and usually (left) very pink/red.

What do you think it might be?
Lack of sun?
