Thanks so much for the replies. Txchickie - all 3 roos - I hope you're wrong too!
I'll try to get an individual pic of the speckled one for further analysis, it hasn't much of a comb at all, but it's hard to tell with that pic.
Still unsure of the cochin, though. I really hoped it was a pullet, I would love to keep it, but I don't want more than one roo. It would be hard to pick between the D'uccle (he's very handsome) and the cochin (IF the cochin is a he). ARRGG! Just when I thought I had it all figured out!
Thanks again, and I would welcome any further opinions!
at 10 weeks old none of my hens had red combs or waddles that size my 18 week old hens combs aren't that red yet it looks like 3 roos to me but i hope not.
