Bob, if I had to guess (and at this point it would be a guess) I'd say the 2 in the middle are Icelandics. What breed are the other 2 delinquents, that may help narrow it down. Also, on mine that hatched, the combs were pretty obvious even at hatch, so look closely at the combs. (unless the other breed you hatched had rose combs, then you're screwed)
Kathy.....it is a CA thing. Most people around here don't park their cars in their garage. They fill their 3 car garages up with crap and park their multiple thousand dollar cars in the street or driveway. When we lived in the city (for 5 years when we were first married until we could afford to buy land and build our house), it drove us nutso!
