I found one of my nearly 3 week old silkie chicks lying in the corner of the brooder. It's barely alive and unresponsive and floppy. The beak is a little twisted now too when it wasn't before. I've given it some poly aid plus mixed with water and have it wrapped up in front of a heater. No signs of any wounds or feather loss. Can anyone give me any advice? The other chicks all seem healthy.
