Thanks! I can't tell a difference in the shade of black yet, as they aren'y fully dry and fluffy yet, but 1 of the 4 does have a black stripe up the front of her shanks, so I'm guessing 3 boys and a girl so far.
This is a photo of my Cuckoo Marans chick when he was about two weeks old. He was sexed to be a she but as all my chicks grew up, it was clear, she was really a he.
And here's a photo of him when he's about 5 weeks old. His legs and feet were noticably larger than the other girls.
Sadly, I had to re-home him. Which was a very sad day for me. I have a small back yard and only have space for 4 chickens so to lose one was tough. And I was so looking forward to those chocolate eggs.
Good Luck with your Cuckoo's. They are BEAUTIFUL birds.
Thanks for the pic of your boy... I've changed what I think... now I think 2 are boys and 2 are girls. One of the ones I was counting as a boy had a little dark on her shanks so I was on the fence with her. But looking at the spots on their heads I've decided she must be a girl, too. If only the Light Sussex could be sexed as easily!!
