As you well know, your Alex was witness to a brutal murder and is in heavy shock and fear for his own life! No question he misses his fellow feather friend and is crying out for her.
Where to go from here? Difficult, very difficult!
- Much of this is heavily dependent on if you had 'any' relationship with your Alex. If so, your effort is in restoring some level of comfort that he is safe there! You're one on one attention is going to be a starting point. Tons of time to get him somewhat comfortable. Likely, he shakes when the dogs are around and/or barking.
- Clearly the dogs and the Parrot never can be in the same area at the sametime, as he will freak-out.
- Very likely he will never want to go back outside for a very long time.
- At this point it is all about him! With great hope he will respond to your vast amount of one of one time.
- Is he eating? If not, major effort in providing 'anything' he will eat to get him started!
I have worked with abused, older Amazons over the years, and what your Alex has experienced is far beyond what they likely had deal with.
My heart bleeds for your Alex.
