This is our first set of chicks, supposedly all pullets. I'm highly suspicious of our white leghorn, though. "She" has a bigger comb than the rest, in particular, and she's been growing the fastest. I wonder if it's just because white leghorns are bred to grow quickly and produce right away? It's possible that my other girls' breeds have smaller combs at this age (4.5 weeks), too - not sure. Anyway, here are pics, your opinions are much appreciated!
