Mille Fleur D'uccle Bantam Chicks, Not Sexed

I love my Mille Fleurs, though they are only 4 weeks old currently. This is my first time raising them and I’m loving every second of it! None of them appear to be aggressive yet and I spend a LOT of time with them. I ordered 3 (straight run, of course) and they sent me an extra! So far, I’m 99% sure that I have 1 male. It already had the largest comb and it’s bright pink. I’m split 50/50 with one of my others, which has a large-ish comb that is still very pale. My remaining two I am 90% sure they are females! They are so friendly! Every time I reach into the brooder just to do something like refill their feeder, the Mille Fleurs jump onto my arm! Then they just lay there, not caring that their “roost” is mobile. ? I love them all so much and am thrilled that they arrived to me safely from their journey completely healthy and still going strong! I have always said that I wouldn’t get the same breed of chickens again because there are so many to try, but I think I’ll have to break that law for these ones! Highly recommend!
