I got 5 straight run Brown Leghorns that 2 of were roos. I also got the 3TTs, 3ALs and 3RSLs pre-sexed. Of course the RSLs were foolproof. I noticed one of my Amberlinks have a much redder comb and wattles, but they are very small compared to the BLH roo who is a week younger than her, so I am sure she's a she. All of the rest are straight run. My BAs look like a 7 pullets and 8 roos. The rest are to small or I just can't tell. My Barred Rocks should be able to be sexed, but... I see all roos, maybe one pullet. I dunno...
