I have started tracking yellow vs silver downed chicks - we have them both here (where the dot on the head is yellow or silver, never keep a rust or full yellow colored Dom chick lol). Will keep you all posted on what the results are as we go through spring hatching. We toe punch and wing band everything, have learned a LOT doing this and raising many many chicks now we know what we want to see on day one, week one, week eight, etc. for them to stick around. The pullet that was in one of those photos I posted was probably missed with that head I would have normally culled her at day one for having a head like that, oh well.
