Hi there, I had seven oldish (year and a half?) Lohman Brown hens. They were ex-commercial hens which I "rescued". I got them in very skinny, tatty condition in December and have since fed them up and given them a pleasant retirement home. They all fattened up and regrew their feathers, and were looking very healthy. Some started laying again (1-3 eggs a day). They have a spacious run and get let into the garden daily to forage. One of my chickens died a week ago. She seemed fine the Saturday, but by Monday evening she was standing quite hunched, in one sheltered place (not walking around at all), looking very unwell, not eating/drinking, and making a strange rattley croaking noise when she breathed in. She appeared to be struggling to breath, like she had something stuck in her throat, often opening her mouth to breath in. We gave her a cuddle, could not feel or see anything unusual, she relaxed and dosed as we held her, possibly breathing a little easier. Next morning (Tuesday) she was dead, in the same sheltered place we left her. I did some reading up on this site, chatted with local chicken farmers and a vet. I concluded it was probably some respiratory problem or bronchitis? Some of my chooks had been sneezing a bit, so possibly they had something which had affected one hen worse than the rest. I put the remaining 6 on a course of antibiotics (in the water) for 5 days. The sneezing might have eased a bit, but it hasn't stopped, and none of them have laid since the hen died and I started antibiotics. Otherwise they seem very healthy, running around happily. I am currently putting some "anti stress immune boosting stuff" in their water. Do chickens need probiotics after antibiotics? If so what is best form (yoghurt, or capsules added to the water)? On Monday another one got sick, wandering into a sheltered spot and refusing to come out for treats. Yesterday (Tuesday) she was moving around a bit, but not seeming to eat or drink, no unusual noises. This morning I checked on her and could hear she is starting to make the croaking sound! I suspect she is going the same way as her sister... The sound is quite strange, somewhere between a crow, a frog, creaky door and a death rattle... Hard to describe. If anyone has had similar experiences or has any advice I would appreciate your sharing. Wishing you well, Alan. PS: I did also consider Gapeworm, but none of those I spoke to thought Gape worm was likely, not even sure if we get it here in Cape Town? (while she was opening her mouth and struggling to breath, it did not seem as extreme as what I read on the site). PSS: It is summer in Cape Town, so warm, fairly dry weather. My chooks have shady shelter under palm trees. I live on a wine farm, so lots of other wild birds around (too many guinea fowl) which the hens may have come into contact with.
