Hi all. I have a new Budgie approx 8-10 weeks (that’s what the breeder said). Today is day 2 and I’m concerned as he is sleeping in his seed container. He seems to be using it as a nesting box. Should I be concerned?

could be just its personality or is actually younger and still needing the comfort of a corner to hide in, then again maybe a bit of separation anxiety from loss of siblings being about- therefore a bit young I would think, just my thoughts
