Hello. My name is Patrice, Trice for short, & I'm in the process of purchasing a DuCorps. He's 4 months old & still being hand-fed formula thru a syringe. I'm a little concerned at this point. Even right after a feeding, Malcolm incessantly whines & sways so he cannot be hungry. I visit the bird store every day to spend time with & bond with him. But the whining doesn't stop!! Any idea what's going on with him? I read somewhere that a DuCorps can do this up to two years then suddenly stop...but no reason was explained as to WHY. Can anyone fill me in? When I picked him out he wasn't doing this. But now the second he sees me he starts swaying & crying nonstop, despite my attention & cuddling.
