Hi everyone. Thank you for your contributions to this site. I live in the foothills of Adelaide, South Australia. I rescued 4 Isa Brown Hens 6months ago. They had a dirt floor iron shed plus a large grassed run to free range during the day. One hen was taken by a fox. I have moved the rest close to my house under a verandah, a large bird aviary for night time then free range during the day. They don't use the perch but have just read on this site that you need to teach them how, so will do. I have straw on the floor and remove droppings daily. I have one hen who has appeared unwell for the past 6mths, her name is Lazzarus, (Lazzi for short). I have used this site for advice and have tried different things and have syringe fed her when necessary. Her poo has always been runny and has varied from brown watery fluid to greenish. Lazzi had a very heavy red mite infestation when I got her so I treated all hens with Pestene powder. They have also been wormed. Lazzi has been near death several times but has rallied unexpectedly each time. She had a slow crop intermittently which I treated by vomiting her carefully each am then feeding her boiled egg/yoghurt. Her crop is now empty each am but still distended. I have never seen her lay an egg. Her appetite is good, I feed her separately now with wet chook pellets, meal worms and yoghurt/boiled egg. She is very underweight, her comb has always looked floppy but not bright, a little dark somedays. Her vent is always dirty with sparse feathers in that region. In short she looks chronically unwell. The other two hens are thriving. Unfortunately I am financially compromised and can't afford a vet. Does anyone have any ideas as to what may be the problem. Thank you so much. Jeanette from OZ.
