The Parrot

Careful there, Mike, I've hand-raised 95 baby cockatiels in a 13-year period. Even as babies, they are smart and would be weaned in about 6 weeks. Of course, adding a little bit of peanut butter into their baby formula helped. That formula was set to a temperature of 107 degrees, and they gobbled it up. You could see it in their crops. 
But then again I had a very good teacher, my grandfather, who owned Wynde Crest Avairys in Springlake, NJ. While I never handled any of his birds, since he had over 8000 parakeets, 1000 love birds, and 5 or 6 hundred cockatiels, all in his basement of his 100+-year-old home. But he didn't stop there, he had ducks, chickens, peacocks, pigeons, and homing pigeons in different barns on the property. Both he and his wife ran the place and thrived. He was a WWI veteran and when WWII came along he volunteered to go to that as well. A true patriot as well.
But what I did do was, to watch how he handled the birds especially, the babies. So I did that for mine as well.
