oh boy! Blanca is a boy!

Blanca crowed on Monday morning!
Rocky crowed on Tuesday and Wednesday morning.
No crowing today...

So, how did I do at guessing so far?

I think I had it figured right by 5-7 weeks.

1 week old (first day home) I guessed 2 wrong.
Penelope had a comb already, but is a pullet not a cockerel.
Blanca, though a very round chick, was not a pullet, he is the first to crow! Ha!
2 weeks old: same guesses
3 weeks: 1 wrong-still thought Blanca was a pullet, but figured out the bred of the others, which helped with gender guessing.
4 weeks: 2 wrong. again Blanca and I feared Teriyaki, since her comb turned pink, but I think she is pullet.
5 weeks I change Blanco to cockerel, which is correct and had 1 maybe, Teriyaki
6 weeks-I am on vacation
7 weeks I have their genders guessed correctly now (I think)
at 8 1/2 weeks we have crowing to confirm Blanca is a cockerel and Rocky also.
