Baby Burt is sooo cuteSorry, I can’t tell much from your pics.
This is a closer pic of some stress bars which are very often seen on babies, they are sometimes due to temperature changes which is what Burt’s were most likely caused from as there had been excessive power outages in the area while he was developing. They basically happen as nutrition is diverted away from the growing feather to other necessary body functions such as keeping warm.
They occur as feathers develop and cause blackened weaker lines across the feathers and are usually a very distinct line with an obvious change in colour and texture View attachment 429486
If I can find some decent pics of bronzing a bit later on I’ll post them unless someone else finds a good example for you.
Thanks @Mizzely , I'll keep a close watch.Hahns don't naturally have black like that, no
Feathers that grow in like that are stress marks. Can be nutritional deficiency, but also can be from anything that caused the body to temporarily take nutrients away from growing a feather. An illness, high stress situation, etc.
Feathers that turn black after growing in are from bronzing. Green in a lot of species is created by little ridges in the feathers that cause light to reflect as green. When the feathers are worn, the illusion is interrupted.
Regardless, a few black feathers from either reason wouldn't immediately concern me. If your bird starts getting more black, then you obviously want to be sure you know if it's on new feathers or not so you can better understand if it's time to worry.
No, but i think over preens his feathers. He has already chewed up his tail feathers.Sometimes bronzing can be caused by rubbing up against something in the cage, or not having enough room to turn around and they are always bumping into something. Is there something he sleeps up against that might be rubbing that same spot frequently?
