It seems that the bird is molting, however in one picture it looks like there may be some type of bump on the cere, can you post a better picture? The cage is in poor condition, the metal is exposed in several places that I can see and it appears that perhaps has been picked on in those areas by the birds, this is dangerous and can lead to metal poisoning. The cage also appears too small for the number of birds you have in it and the contents are dirty. Please remove the nest like vessel in the cage.
The purpose of this forum is to promote the BEST PRACTICES in the care of budgies for their optimal Health and Well-Being
The budgie needs to bee seen by an Avian Vet. It has a large growth above the cere on the left side.
Avian Vets have special training to determine the cause of symptoms resulting from illness or trauma.
This is important as "regular" vets will often overlook symptoms that are quickly obvious to an Avian Vet.
When you rely on anyone who has not had training in Avian diagnosis and care, you may be delaying effective treatment.
This can prolong suffering that may be avoidable.
The bird will often require a more intense, prolonged treatment with a poorer chance of full recovery than it would have if you seek prompt professional diagnosis and treatment at the first sign of illness. If there are no Avian Vets near you, please find an Exotic Pet Veterinarian with experience in dealing with small birds.\
