Hot beak, warm feet. ?

my bird has had a hot beak for 2 days now. When i put my finger to his beak i can feel the heat bouncing off my baby. His / her beak is hot and when he put his tongue on my finger i could feel hot breath. His feet is warm too.

He is eating and moving around normally and He is active he has been playing with his foot toys today so nothing different has changed here. I give him a shower spray using mist bottle today and he dried pretty quickly. House is not too hot just right.

His poop is green with a bit of white in it. Is there anything i should do or look out for. ?

I have never felt his beak this warm since i have had him so i have noticed something new which is why i am concerned.

Something else new that i noticed is the way he sleeps. He has always slept with his head over his shoulder tucked into his feathers but now when he sleeps he droops his head down, is this normal ?

Gabbana is 21 weeks old. Still a baby. He eats the parrot mixture of seeds, nuts etc, he loves apple and broccoli which are his favourite. He has kale/ spinach leaves, and has had a couple of blueberries today too just to add.

He has not ate anything different hmm. Any ideas ?
