I have perused the site looking for answers but couldn't find what I was looking for. I have a 1 1/2 year old barred plymouth rock who started letting out a squeak sound for the past few days. She seems very healthy, clear eyes, no nasal discharge...almost sounds like hiccups. I thought she might have something caught in her throat and tried feeling around including her crop and I can't feel anything. Has anyone had this problem?
