She is an 8 month old Orpington. She has been sitting in the nesting boxes the past couple days but I thought she was just laying an egg This night I went to collect the eggs and she didn't look very well when I seen her face & was barely moving at all, I picked her up & to my surprise she was so thin I could feel her chest bone, brought her in the house & made her her own area with food (oatmeal+sugar+chicken feed mixed together) & water with a little sugar because she isn't eating very much but is drinking tons of water. She looks like the other hens gave her quite a beating, All the feathers on her head are gone, feathers are missing in other small areas too, small blood spots. Fortunately she perked up a little since she has had lots of water & a little food in her but is not moving much. I checked her poop, its diarrhea brown+clear liquid. I was reading about this online & people were saying that some hens lower on the chain get chased away from eating & drinking, pecked at & chased away that they hide & get scared to eat, idk if this is the case but she is a smaller Orpington than the rest. She doesn't look like she has any noticeable internal problems, no heavy breathing so far. from the looks of it she was starved, how do I handle this? Do I help her eat like dip her beak in food? I know that she wont be able to eat a lot because her tummy must have shrunk, how much food should she be eating at this rate? & has anyone else seen or had this happen? What else could be wrong?
