Unfortunately there are several breeds of chicks that look similar to your brown one. I have both Welsummer and speckled sussex chicks. Both look similar. I lean towards Welsummer. I don't remember mine having the white breast though. I will try to find time tomorrow to check them and reply. My brown leghorn last year also looked a lot like this.
Sheaviance1 - This is definitely not not a Gold Laced Wyandott. If your GLW looks anything like this then you got something else. By this age you should see the lacing of a GLW. The head color is also wrong for a GLW.
