We had 5 hens and 1 rooster. One of our long island reds died yesterday after we noticed she was having trouble breathing and moved her to a separate pen. Now one of my white hens is acting very lethargic but still eating and laying. They are just over 2 years old and this is the first illness we have had. We feed them pellets and water and sometimes fruits and veggies. We never immunized them either. We picked up some over the counter salve and some apple cider vinegar to try and treat. What should we do? We ate some of the eggs before we knew they were sick, is that ok? Is it ok to eat eggs from sick hens? Thank you!
