My silky guys are 3.5 weeks old now and growing more every day. As they get more mature, I'm beginning to face the reality that at some point I'm going to have to weed out the roos. (although.... DH DID say today, well, if we're going to keep a roo, we'll have to keep that white one if he's one...wish I had my recorder going when he said THAT!!) So, I'm looking for tips on telling gender of Silkies. I know they can be sneaky, but are there any tell-tell signs short of crowing and egg laying?? Thanks!
