Strawberry's NOT sneezing or have any other symptoms, but she is staying in the chicken stagecoach nesting area and not feeling good. She's up for grape and corn treats and comes out when it's warmer outside. I put a heating pad in last night since we had a freeze. Is this a tumor? The huge swollen head now got some bloody spots as I think she's clawing at it. Do I need to euthanize her to end her suffering?.She seems like she's having some pain. I think she's 4 or 5 yrs old.
