Hello,My name is Linda and I am baffled! My Lilybug ( Japanese bantam hen) is in need of help. It started 3 months ago when my Silkie went to her nest to lay an egg. We thought she decided to sit until we discovered the following evening while getting her out for dinner that she could not walk. I feed her through a syringe, held her up so she could get her own food and water, made her a baby walker out of a cardboard box so she would not be constantly sitting on her legs, and massaged her legs to help circulation. About a week or so later our oldest Blacktail Jap hen started gasping for air but still ate and went about her daily fun. We decided to have a mobile vet come check out all of our babies(chickens) since we now had 2 that are ill.She checked to see if maybe our Silkie( Fuzzy Fuzz) was egg bound and she wasn't. She also said that our eldest hen Mandy gasping for air was probably due to stress. We knew that wasn't the case because our babies are treated like royalty and love us! The vet gave me Baytril to give for 10 days. After the second dose Mandy passed away. Baytril didn't help Fuzzy Fuzz either. I just continued caring for Fuzzy Fuzz myself and about 1 week ago she has had a complete recovery. After Mandy passed away our Jap hen Lilybug started doing the whole gasping for air too, but only while lying down our being held.She too went about her fun filled days as if nothing was wrong. We took her to a vet anyways and the vet said she heard crackling in her chest and put her on Clavamox thinking it was pneumonia. We gave it to her as directed and still gasping for air.Took her to a 3rd vet and they took xrays. They said her bones look weak and it seemed she was lacking airsacs? But also said it could have just been the xray image making it look that way. She also thought pneumonia and put her on 10 days of Baytril again and Bene-Bac. Lilybug is still gasping for air. Finally I noticed one of my Wheaton Japs just wouldn't stop picking at one of my Buff Japs vent area, so I decided to checked it out. Here she had bugs! Not sure what kind? I checked all my other babies out and they had them too (including Lilybug) We instantly dosed them with ivermection and I also put vaseline around there vents for relief. Lilybug still gasping for air but now she isn't eating well and sometimes looks lethargic. We started to put vaseline on her vent area at night because it seemed to bring some relief for the breathing which instantly made me think that all this time bugs was the cause of the gasping. Her not eating got worse so we stopped putting vaseline on her thinking she was ingesting too much vaseline while preening. Instead we started manually putting DE Earth on her because she is too weak to fluff in it on her own with the other babies.Oh... looks like the bugs are gone now.We treated everything! We also have her on Nutri-Drench twice a day( been on it for 9 days orally instead in the water bowls),I have been syringe feeding her baby food and yogurt along with 50% water 50% gatorade for fluids to keep hydrated. All of our babies get scratch grain, layer crumbles,rolled oats, meal worms, and lettuce daily. I've also been offering hard boiled and and have been adding water to their layer crumble hoping it would help the water intake.They all have been dewormed as well. I keep her on a well padded heating pad every night and started her on The Missing Link Ultimate Poultry Formula on Feb. 27th. I was considering Nutrical for puppies and kittens because she is getting so thin, but decided against it since I do not know for sure if it would be safe. I'm thinking she may be anemic because of the bugs so the vet told me to add sugar to their drinking water. I've been doing that every other day.It all comes down to not knowing why she gasps for air only while lying down and being held and why she is now eating poorly with lethargy. No one can give an answer other then pneumonia but this has been going on for over 2 months now. Wouldn't she be sneezing or have discharge or even have died if that was the case. Any help is wonderful! I've tried everything I can think of and I am beginning to feel like I'm failing her. I love her so much! My Lilybug needs to put weight on and is in dire need of a good nights sleep! ME TOO! Thank you all!
