I am hoping to get some advice about my Bantam cochin, 3 years old and 3lbs. She has had a running beak, clear and not smelly that comes and goes. This morning I noticed she has a faint click sound when she is breathing...not all the time and will breath through her mouth occasionally. Thinking she is fighting some type of illness/cols that is getting worse. She didn't want to eat a lot this morning and she is a little sleepy, but nothing too bad yet. Please advice how I should treat or do I need a vet before I do?
