It could be blood feathers fallen off, because new feathers usually have blood vessels in the core. Is he/she pruritic? If the lesion is itching, it could be things like parasites, allergy. Moulting can be one of the cause too. For beak and feather disease (PBFD), the feather should be dystrophic, and the lesion should be predominantly in the primary and tail feathers§@ªÌ: scylam ®É¶¡: 2011-10-15 12:05
Thanks for the reply. Could you articulate on why PBFD is unlikely? In case of other means what will be the treatment? Finally, do you recommend bathing to medium size 3 months old parrot baby bath or mist? Thanks again.§@ªÌ: louisa20047 ®É¶¡: 2011-10-15 14:12
There are two form of PBFD, acute vs chronic, it is like human AIDs, most of the damage is done thru immunosuppression.
Acute = seen in juveniles, around weaning age. These bird are usu lethargic, fluffed and anorexic. Hamematology may show pancytopaneia (decreased RBC, WBC, platelets) and non regenerative anaemia.
Chronic = progressive replacement of normal feathers with dystrophic feathers
In this case, it could still be acute PBFD, but not chronic form
Hope ur baby bird get well soon!§@ªÌ: Cherryyeung1 ®É¶¡: 2011-11-10 23:56
