Do you have any info on euthanizing them and put them to sleep painlessly? I'm losing her to the egg yolk peritonitis. She smells bad and she's not eating and she only drink if I nuzzle her nose into some water. I tried the Essential oregano/rosemary oil in coconut oil, maybe it was too strong for her even though I diluted it and coconut oil.
I'm in a try to keep her as hydrated as I can to keep her comfortable. We only had times to use no calcium glutamate. I only have a bone up from jarrow which is probably too strong for the chicken
Do a search here, and on the web for ways to humanely euthanize a chicken. There are many ways, and many opinions. The right way IMHO is whichever way you are most comfortable with.
If you are not comfortable with a method, it increases the likely hood of botching it and making it more dramatic than necessary for everyone. It's really a personal decision that you must make for your peace of mind. It's a really good idea to have a plan ahead of time for when the day comes. I can say from experience that it's never easy, but it gets easier. It's just, unfortunately, part of keeping chickens.
