Your hawk has red flecks in her mutes, flicks her food and has poor appetite. She probably has?

The symptoms described—red flecks in the mutes, flicking food, and a poor appetite—suggest the possibility of coccidiosis. Coccidiosis is a parasitic infection caused by organisms called coccidia, which can lead to gastrointestinal disturbances in birds. The presence of red flecks indicates blood or a possible inflammatory response in the digestive tract, and the behaviors of flicking food and poor appetite are common when a bird is experiencing discomfort or pain due to illness.

In contrast, while apoplexy can cause sudden deaths and may present with other indicators, it typically does not correlate with the specific digestive symptoms described. Aspergillosis, a respiratory infection caused by mold, usually manifests with breathing difficulties rather than gastrointestinal signs. Bumblefoot, a condition relating to foot lesions due to pressure sores or infections, would not cause gastrointestinal issues either. Therefore, the combination of the symptoms provided aligns most closely with coccidiosis, making it the likely diagnosis in this scenario.
