My two chicks are indoor chickens so they get treated more 'spoiled' than normal chickens. One day I was holding one and it seemed very cold, so I took a hair dryer and blew him with it. Soon he started to fluff up and fall to his side with his legs tucked up and wing folded up. Is this normal?
No no this is not normal. Please watch the bird closely listen for signs of illness. How is its breathing. Is it eating alright? That is a sign something is not right. Keep a close watch for other symptoms. How is the bird acting now?
The way you described it falling over and tucking it's wing up reminds me of how my chickens react when they sunbathe and when I placed chicks under a heat lamp in the brooder. It may have just been enjoying the heat, but with the little info you gave I'm only guessing here. What happened after you switched the dryer off? Did it get up and walk around, or stay down? Off topic: I love your avatar pic! What's the story?
I was thinking the same thing, that he may have just been enjoying the heat, like birds do when they go out to sun bake. But usually they stretch out one leg and one wing. Speaking of which, since these are inside birds, you need to make sure they get outside regularly, at least enough to get some sun. Birds require UV light in order to process vitamin D. Sunlight through window glass is not sufficient as the glass filters out too much of the UV rays. Lack of sunlight will cause a deficiency.
For my avatar, I had found a owl down at my grandparents house and he was very injured so I took care of him until he was better. I just let him go a month ago back at my grandparents house when he could fly again.
