Help! my chicken Bunty is very ill and weak.
Her symptoms are small comb and gaggle, pale face, tiredness and squinting, very underweight, very small droppings that at one point became white and back to normal colour, messy fluff beneath vent, poor balance, ruffled feathers, huddling and she distances herself from other chickens. She seems to eat enough when ime around but when out in the feild she tries to sleep. What could this illness be?
Also, another chicken sneezes and very small amount of clear bile appears around her nostrils but doesnt turn crusty.should i be concerned?
Both have had routine worming and vascinations against salmonella and other diseases about four months ago.

Hi
I'm wondering if she's eggbound. Signs of eggbinding include: reluctance to move or walk, easily picked up (despite not necessarily being normally easy to catch), draggy wings, ruffled feathers, loss of appetite, white or clear discharge from vent, smallish or watery droppings, closed eyes.
Fill up a large tub with water- about the temperature that you'd wash dishes (not scalding hot by any means but not cool. Remember a chicken's body temperature is several degrees celsius warmer than our own). Fill up the tub so that when you stand the hen in it, her abdomen is submerged but she's not wet over her back. You want her to relax and stand- you'll probably have to stand with her. Do this in a very warm room- run the shower on hot water for a few minutes before bringing in your hen- if she struggles madly (usually they do not and seem to enjoy it) the you are not accomplishing anything- dry her off as best you can and put her under a heat lamp or on a heating pad.

There are a couple of other possibilities, including coccidiosis (usually bloody diarrhea), lymphoid leukosis (shouldn't have come on so quickly, but it is possible), poisoning (any compost, dead animals or poisonous plants/chemicals around?)

Thank you for replying!,
Shes getting better as we are treating her.
She has been diagnosed with Hypothermia ue to cold snaps.
We gave her a warm bath and cleaned her vent area.
Shes getting better.
