I have 15 week old and 8 week old BLRW chicks that are from 2 different breeders. Two chicks in the 15 week old group have crossed beaks (parrot beak) and 1 chick in the 8 week old groups beak is just starting to cross. The 2 chicks with crossed beaks (1 pullet, 1 rooster) in the 15 wk old group are from the original Lowell barber lines (from Catt's stock) and the 1 pullet in the 8 wk old group is Paul's x Foley lines. I have noticed that the 8 wk old pullet has the same head type as the two chicks with crossed beaks in the 15 week old group. When looking on Feathersite at the picture of a BLRW pullet from Catt's birds, I see that the beak looks more like a sparrow's beak (no overhang) which looks un-natural. My question: Is this a genetic problem coming from a gene associated with this head type, and am I going to have problems with crossed beaks if I breed these two groups (not the crossed beaks, they will be culled) to one another? Your experience/opinions would be greatly appreciated!
