Hi - I'm seeking some advice please on what might be wrong with one of my girls. I have 3 Isa browns, one of who I recently rescued from a neighbour intent on killing her because she lays soft and rough or no shell eggs. Initially I thought they "neighbours" chook had a calcium absorption problem but now I starting to think it is a little more sinister than that, as over the last 5 days my oldest girl had become sick. So now I am thinking I might have introduced some thing to my little flock by taking in that bird. I've done a fair bit of reading about soft shells and discovered that it can be caused by a influenza virus type illness. My old girl has been "off" for about 5 days now. To begin with she was just sluggish in her day to day activity and stopped laying eggs. Then she seemed to develop a lameness in one leg, with no indication of trauma, or injury to the leg, and has completely stop her daily free ranging which she used to love. About 3 days ago I notice a white lump on her left cheek (I've attached a photo to try and show this) which seems hardish to the touch. She isn't sneezing, no mucus and no difficulty breathing as yet....but I can tell she is getting worse not better. She is still eating and drinking but not with her usual vigor. I have a sneaking suspicion she has some kind of Gram negative infection but I'm not sure and this is were I would like some other options/thoughts on what the problem might be please? And what I might do to fix it? The neighbours chook seems fine other than the soft or no shell issue, and my younger girl is still full of beans and the only one laying at present. Appreciate any advise. Cheers from a Worried Mother of 3.
