This is my first time raising chicks! I have a polish chick 4 weeks this Sunday that has a bald spot on its head and is a red. Is it just new feathers coming in? I have attached a picture.
Have you spent time observing your chicks to see if there is any picking going on? I ask as those birds with feathered feet, heads, etc are frequently targets of extra "attention" from their flock mates.
