yep... the hen does not care if the cock can fly 400miles the fastest. she will look for the aggressive cock that will protect her and her next box. The cock that struts his stuff the best. Personally, i think sometimes giving mother nature a nudge in the right direction is needed.
of course if you have a loft full of 1st placer... then hell ya... let them pick eachother...
best example... dang rollers mate like crazy in our old bird loft. finially had get rid of them.
