3-week old budgie sleeping position

Hello! I am new to this forum so before anything else, I want to thank all of you because I got big helpful tips here as I am a beginner when it comes to budgies and birds in general. 😄😄😄

We have these two 3-week-old budgies at home named Tori & Bacon. I noticed just now (it’s currently 11:20PM in the Philippines) that Bacon sleeps on his tummy in the corner of his box. He weighs 31 grams. Bacon was energetic this whole day and he likes to call/chirp/try so hard to fly out of his box to play every time he sees anyone looking at him.

Also, what does rapid breathing looks like for a 3-week-old baby budgie? What could be the possible reasons for this rapid breathing? I noticed that Bacon’s breathing while sleeping is considerably faster than that of Tori’s but this is the first time it happened and I’m thinking that maybe it’s because he was laying on his belly. Tori is sleeping upright.

Thank you so much for reading up to this point! Hoping for answers from the baby budgies experts Unfortunately, there are no avian vets near us. The lockdown in our area made it even more difficult to find one in the city, which is 5 hours away from where we are.
