We started Cracker on a daily course of organic red palm oil spread on toast which he devours, because of the positive reports we've read about plucking macaws treated with red palm oil. Of course there's no way to know absolutely whether a change in environment, a proper diet, the red palm oil, or a combination of the above contributed, but after two months we are seeing significant feather growth on Cracker's body, wings, and legs. Although we continue to find plucked feathers on the floor, the volume seems significantly reduced from when Cracker first came to us. The next photo shows the change over the past six weeks:
Needless to say, we're keeping our fingers crossed! Our next step to to address Cracker's socialization. Mr. Cracker still won't less us touch or handle him, but we are told his previous parront was able to step him up on his arm whenever he wasn't on his cage.
