x2 When I first got my chickens, I had a similar problem. I brought her in, gave her baths, etc. Didn't know about this forum. I had to euthanize her also. Thankfully, II'm sorry for your loss and would like to thank you for having the courage to end her suffering and for doing the necropsy. I believe it's posts like yours that people can really learn something from. Thanks again, your story will be a reference for me.
have a son who is willing to come and help. Mine were Delaware hens and they all lay enormous eggs. Looking forward, I now take preventative measures to stop this
from happening.and if someone misses more than a couple of days of laying, I check them out. I went in to having chickens as my parents did. Twice a day they watered
and fed them, collected eggs and I rarely remember them losing any. (1 rooster got hit by a car) I am so sorry about your loss.
