I would suspect a vitamin/mineral deficiency. If it were my bird, I would be giving it a calcium supplement as well as small bits of a Brewer's Yeast tablet each day. Were you hand feeding this youngster or was it already eating on its own. If you were hand feeding it, it would be helpful to know what you were using .. Kaytee Exact or similar or something else?
The growth issue is something else to consider. It is possible that this little one is suffering from paratyphoid (salmonellosis). A vet should be able to tell you if this is case in pretty short order. Should paratyphoid be found, then the parents need to be treated for this as they will continually pass it on to their young.
