I have a Cochin who is a little over a year now who recently got what I think is an impacted crop. The past three mornings when I let her out her crop was full and firm. Yesterday and the day before I let her do her own thing because she was acting her normal self. Last night I had her drink water with olive oil and I massaged her crop trying to clear the impaction. She's pooping normalcand acting completely fine but her crop is firm and not clearing. What do I do?
