Hello All! I am in desperate need of advice. I started with 4 hens in May. They did great for a couple months until 1 fell ill. I brought her to a vet where she was treated for 36 hours and did not improve. I then had her humanely euthanized and a necropsy performed. As I awaited this result, a fisher cat ate 2 hens. I was down to 1 hen when I received the autopsy result- she died from listeria. I immediately got my only remaining (and asymptomatic hen) on prophylactic oral antibiotics, Tribrissen. She is done with meds and is thriving, but is all alone. I am ready to get her some buddies but I know nothing about listeria! Because she has remained asymptomatic, can I assume she is not carrying the bacteria? Do I need to bleach the environment? If so, how do I properly do it? Will her eggs be safe for me to eat? I appreciate any advice, I feel lost and do not want this Wyandotte to be alone, but I also do not want to knowingly place other hens at risk. Thank you for any input!
