Omelet is a 7-1/2 Buff. 2 days ago she started acting a bit lethargic and then yesterday her comb turned bright red and laid over to one side. This morning it is slightly purple on the back side and she is still pretty much standing in one place. I know she is a old hen but any thoughts on what I can do to help her just be more comfortable in her final days. I did start her on amoxicillin yesterday evening and gave her a second dose this morning.
