I have a hen with breathing problems & has lost her voice.
What do I need to do to help her & can she be helped?

Welcome To BYC

Can you get a video of her? Upload to youtube and provide a link.

How old is she?
Does she lay eggs - all normal?
Any other symptoms like bloat/swelling/fluid in the abdomen, watery eyes, mucous, sores or cankers inside the beak, crop not emptying completely overnight?
