So have I. Grey tabbies are one of my favorite breeds, but I had a few Calicos. One of them was the most loving little girl you'd ever meet- Until she became spayed. Then she turned into a murderous freak.
Awe, I'm sorry Hopefully your birds' tail feathers will grow better soon. My bird had lost a few of his and when they grew back, he was in a cage that was too small so it broke his tail feathers (but he was only in the cage to sleep and we ended up getting a much bigger cage)
Also, don't worry about your English. I'm good as long as I can fairly understand you
