Please help with lethargic hen?

I have a 16 wk old easter egger. She has been very slowed down for 2-3 days. Puffed up around the neck. Wings and tails drooping and her she keeps her head down. No obvious signs of injury. Does free range and there is oleander and wisteria on property. Husband also throws food scraps into coop and leaving them to compost in deep litter. Water did can did get a little slimy once. Rest of chicken are doing great. She can't walk fast or keep up with other chickens. Her tail was bent to side the previous two days. She doesn't seem to be eating the starter food, but will eat yogurt, egg and fruit. I put her in a crate yesterday to rest and watch her. Today I opened the door to see how she would do, she came out and went back in. She doesn't seem interested in water either. I added electrolytes to it today, but not sure she is getting any. She does free range, could she have ate something toxic? I don't know the symptoms? Any ideas out there?

Forgot to add that she has started breathing with beak open and her crop or underneath beak seams to be twitching. I did find evidence of them pecking at new sprouts of wisteria, but they all have and the rest are fine. My husband had also been sort of throwing food scraps into coop and leaving them to compost.
