This might be a surprise, but my Leghorn/Cal.White are my smartest birds. Technically they aren't pure White Leghorns, but actually a California White which is a Cal. Grey X Leghorn cross. There was no Cal. White breed listed, or one I could find, so I'm posting here. They are very much like Leghorns in most aspects. Without the black specks in their feather I wouldn't be able to tell the difference. But anyway, from the day I brought them home as chicks they knew where the food came from. . . . .me. Now at 21 wks they will follow me and one will jump on my lap to eat. The first one to lay started at 20 wks. OK for this breed. The other seems to be slow to the draw. They are not very flighty which may be a result from the Cal. Grey blood in them, though they can fly well if they so choose. Overall a very good breed.
