We have a Cornish X like that this time around. Out of 200 of them this one is very tiny. They are three weeks old now and ready to leave the brooder for their outdoor hoophouse and pasture. This little guy can hardly reach the water but is extremely active and looks very healthy.

Seems like he will be able to go right through the holes in the electric mesh fence!

I had a chick like this about two years ago...looked healthy, etc. but at the age of one week just seemed to stop growing. At three weeks she looked like a one week old, development had stopped. She did eventually fade and die, so I just tried to give her as good a life as I could in the time she was with us. I figured as long as she wasn't obviously ill or suffering I owed her a shot at making it. I never did figure out the cause, and out of the 150 or so chicks I've hatched over the years, it was my first and only chick to do this. She was a Dark Indian Cornish Rock/MilleFleur mix if that helps any. I suspect it was the Cornish blood that caused this.

Check your chicks for signs of coccidiosis, parasites, etc., that's all I can suggest.

Good luck!
