I adopted a umbrella cockatoo from a breeder recently on 2 feedings a day. I handfed my macaw years ago no problem so I thought I could handle one more baby. well...he doesn't want to eat his formula.I got him to eat some but he doesn't beg for it and kept running away. is it the syringe? do I try a spoon? is he ready to be weaned? he turns 15 weeks tommarow. I have been offering chop and fruit (he hasn't touched it) and pellets millet nuts and nutriberries. those he is interested in. I'm worried it's too soon. please help!
