So my husband and I got 8 stright-run, Black Australorp chicks and I'm worried that I have 7 roosters on my hands. They were hatched the same day so I assume that they are growing at about the same rate, but I'm not sure. 7 of my chicks are showing a slight comb but from what I've read, the hens have a small comb too so I'm not sure. Two of my chicks are growing much more prominent combs AND wattles, so I'm pretty sure I have at least 2 roosters. And one of my chicks doesn't look like it's got any comb at all. Does this mean she's a she or just developing a little slower than the rest?
Here is a photo of one of the chicks with comb and wattle:
And here is one that has a small comb and no wattle:
And here is the one chick that has nothing:
Did I end up buying 7 roosters and only 1 hen?!
