I know, I know, it's early - but my kids and I are enjoying taking bets on boy vs girl. This is our first time hatching 3 of our own eggs with a broody hen. Black Australorp father. Not sure what hens they came from except chick #3 - posted before and must be from a sl wyandotte. One of the others hatched from an olive egg. There are 2 pics of each chick. What are your thoughts? They are almost 4 weeks.
