I would just like to say that first I am sorry for your loss. I really think that people should not criticize someone who chooses to cull a sick chicken with a respiratory disease especially with a swollen pus-filled eye. I realize that many people here will medicate and treat sick chickens forever, but we should give helpful suggestions when someone wants to give medications, but then we need to respect the person's choice if it is to cull. I just read my bleach bottle, and guess what? It says it kills 99.9% of household germs--seems like that is equal to Lysol. There are actually 2 kinds of Lysol by the way--1 is a cleaner, and the other is a disinfectant.
