I thought I would take a peak and to my surprise there were two young in the nest. They looked like Fire finches, but I wasn't sure

On the weekend out came two young fires and the parents as well as the Cordon were helping


This morning just before going to work I went to see if all was well and nearly fell over when I found three young Fires flying around the aviary

Two of the Fire finches have basically no tail feathers. Is this common and will they grow once they moult or mature
