I am not a breeder. Last year my wife brought home two budgies that some lady did not want anymore. The hen never really wanted anything to do with the cock. As it started getting colder I put in a towel into the cage so the birds would stay warm. I also started putting a towel over the cage at night to retain the heat in the cage. The cock deciced he really liked the towel and started have "humping" the towel. A month later mom started laying eggs. At that time I figured I better get a nest box for her.
I moved mom to the small cage after I saw her plucking their feathers out and one baby had blood on both sides of his wings.
I keep dad and the babies in the big cage but he rarely approaches the nest box.
Mom would chase him away from her all the time and she would not let him eat. I'm very surprised they had babies.
I feed mom a variety of different mixed seeds.
So the hen was plucked as a baby. I asked so many people why she was bald on her front and back. Thanks for finally solving the mystery for me.
When I put all three birds in mom's cage I noticed she will feed the oldest, second oldest and then sometimes the youngest. She has been going after the youngest more often, plucking his feathers and not feeding him too much. Mom will feed the birds for a while and then start plucking a feather here and there, going to eat more seed and plucking more feathers or feeding one of the older babies.
I feel bad for the youngest since he has splayed legs and can not get around to well. I put a hobble on him but one foot is still turned towards hid behind. I noticed a what looks like a fluid filled sack with some yellow stuff floating around in it on the side of the babies back. I assume the yellow stuff is fat. It looks like a big blister. It looks delicate. What is that?
