My Little Pet, Gelatik or Paddy Bird

My pet pet bird, a rocky bird or a paddy bird. I named them from the smallest name Tan, Tin and Tun.
Their age from first hatching is approximately one month.

I found them right in the yard, precisely in the nest. Their parents made a nest inside the bamboo which basically I put the bamboo to be hooked to make a nest. and the result i get them (tan, tin, tun).
