Not my lines, Ron, I have never sent birds to you, and have not bred Blue Light Browns for several years. If they went to someone else a long time ago, they would not longer be "my lines", but whoseever lines you got your birds from. AND you do NOT want a pair of BLB--always must be bred with LB, not BLB together. "Blue tail-- Black tail Dutch??, not Dutch varieties. Hope you can identify your birds and get some correct ones. Good luck.
