I hatched out 13 lavender orps out of the 13 I have 5 I know and maybe 6 roosters. These birds are only 9 weeks old right now. I'm not wanting a show quality bird but would like nice colored, quality and tempered birds to sell. I know the lavenders can have the split feathers, is that something these young roosters will show or is it just a gamble as to if that gene will pass on? Should I let these birds get a little older before trying to determine which one is the best?
