Make sure she’s hydrated and not too hot. My older chickens sometimes get dehydrated and can’t walk correctly but this has never occurred for me in a younger chicken.
They’ll definitely struggle when cleaning them but you just have to hold firmly but don’t squish them. I would try to clean then as soon as possible since they’ve been clogged up for a while. So sorry about your other chicks that didn’t make it and best of luck to the rest!
When I’ve done this in the past I made a pen where the older and younger flocks can see each other but can’t get to each other. Mesh or chicken wire works best. Once they’re almost as big and as fast as the older ones is when i put them together. Do you have roosters? If so i would wait a bit...
If you have anywhere a rat can get under and nest try to clean it out and get all the junk out from under there. If you do, don’t forget to wear a mask the dust and feces from rodents can be very harmful to humans. I hope you can get them dirty things out of there.
Sometimes my hens will just decide to curl up or roast in random places for no reason. You might want to check in brooks or crevices around your area. Again it’s not uncommon for a predator to come and get her although they usually attack during night. Do you close them in every night and if so...
I’ve used Apple cider vinegar in my chickens water numerous times with all good effects. Either cause of illness or just to keep them healthy works well either way. However I’ve never used garlic but I have read that it’s beneficial.
It now will not get up our wake up. It’s completely limp and it’s just laying here still gasping and occasionally spasming. It’s doubtful it will drink so i can give it electrolytes our hydrate it. I don’t think it will last much longer. :(
