I went to get my new chicks yesterday. I was to pick up two Welsummers and one other. The lady who I got them from had, among others, also ordered Brown Leghorns. They arrived all mixed in the same box. We stared at them and sorted and re-sorted for 30 minutes trying to separate the Welsummers from the Leghorns. At that age it is practically impossible. It was easy to narrow it to about ten. After that it was anybody's guess. Eventually, I just has to roll the dice. I also grabbed a Gold Laced Wyandotte. Now I just wait. Fingers crossed that they never develop that tell tale white ear of the Leghorn. Does anyone know at what age I can expect them to develop their white ear if they are Leghorns?
