I lost a hen in October. We came back from camping and found her dead. Our animal sitter said she had been fine. A few days later, another hen became very ill. I took her to the vet and got her on Baytril and quarantined her and she made a full recovery. I thought we were in the clear until my rooster died two days ago. He was fine one day and dead the next. We are heartbroken and confused. They have a nice coop that is part shelter and part outdoor enclosure. We make sure they have a heat lamp on at night. We just cannot figure out what is going on and are afraid of losing more chickens. Now we only have two hens left. We would like to get more but don't want any more to die like this. Do you have any ideas?
