Need help with sickly chicken

[Saqqara]

Hi all. My 3 yr old hen has been sickly for over a year. She was picked on by the other hens and we now let her free range during the day and sleep in a dog crate on the porch at night. She stopped laying eggs more then 6 months ago.
recently, my husband noticed she was sitting funny and when we examined her found she had fly strike. We treated her for several days picking out the maggots, giving her salt bathes and using vetericyn on her wounds. She seemed to get better and started walking around eating well. We have also been giving her probiotic and vitamin water.
Now, she has started the head bobbing from side to side, and has stopped eating again. My husband picked her up this morning and clear fluid came out of her mouth.
does anyone have any suggestions?

I’m watching her and she is drinking quite a bit.

Please tell us where you're located. Your weather may be playing a role in your hen's health issues.

It sounds like she could have a crop issue. You can only verify that by taking up all food and water after she goes to roost, and then check her crop in the morning before she eats or drinks. A full crop at this time of day would point to a crop disorder. https://www.backyardchickens.com/ar...w-to-know-which-one-youre-dealing-with.73607/

If you are having hot weather, this regurgitation could be from over consumption of water. But it's still a good idea to rule out crop issues by doing the morning crop check.

Hi. We live in northern Georgia. While it’s warm and humid, it isn’t unbearable. She has been sleeping in a box at night in the house Under a heat lamp. Why the heat lamp? She seems to like it. She can move away from it, but she stands under it.

She is probably suffering from a crop issue caused by cancer tumors or s chronic reproductive infection. That's just a guess going on how long you say she's been acting sick. Eventually, a chronic issue such as infection or cancer will affect crop function.

It still needs to be treated, though, if you determine by a morning crop inspection that her crop is not emptying. That article link I gave you will help you identify her crop issue and how to go about treating it.
