So I have an Isa Brown hen who has been pretty sick over the last 2 weeks and I have had to intervene. She is 4 years old (almost average age for the I/B's) and noticed that she wasn't eating and spent more time standing still and sleeping. She still chirps all happy when I pay her a visit (I have her isolated now) and does eat a small amount of pellets soaked in water, bread, or even vegetables. She used to have diarrhoea which consisted of white water, but now I've started to feed her enough its more a solid brown normal looking colour. Though one of the main concerns is now, is since she lost a lot of weight over these 2 weeks, its really started to take toll on her muscles, making it very hard for her to move around. She will sit still all day in the small enclosure, and might take 1 or 2 old man steps before collapsing again. This hen used to be very active, friendly and excited but now, her quality of life has deteriorated a load. I have also noticed that when I give her food / water, it sound like her stomach is grumbling, like the food isnt working for her. Is this related to anything? About a week ago she wasnt very very crippled, but was still walking like she was egg bound, but I checked multiple times and she wasn't, I also gave her the spa treatment and put some Epsom salts in her water to flush her system. Any suggestions, treatments, cures? Anything is appreciated!
