Yesterday I noticed my hen walking around slow and sluggish. I then realized her crop is full and there is a fowl smell coming out of her mouth. i gave her a little bit of olive oil to help her throw up, she did a little bit but not much came out. I put her in the coop for the day with little food and water. Gave her the same amount of food this morning Shes been popping greenish as well In the water I put a little apple cider vinegar to help loosen what is stuck in there. As well as giving her some Olive oil. Now that its the evening shes having a hard time breathing. I gave her a little bit of plan yogert mixed with olive oil. Ive also been massaging her. What can i do to help her shes having trouble breathing.
