I have 5 porcelain D'Uccle & 4 Dominique's / leghorn they are 5 weeks old. By the looks of all the posts I see I'm not the only one impatient about finding out the sex. I am guessing like me everyone wants to keep only one rooster and doesn't want to get attached to the ones that will have to be given away. At what age will I be able to tell for sure or are we talking eggs and crowing? The D'Uccle's I can't really tell yet but the other 4 Dominique's I am sure I have 3 roosters. Here is my question, can I keep one of the dominique/leghorrn roosters or should I keep a D'Uccle rooster. I would like to keep the dominique but is that a good idea with the smaller D'Uccle hens?
