Yes, I had thought of that, but I was a little worried about not being able to sell Leghorns as most people seem to want brown egg layers.
That and my husband would have a bird (pun intended) if I ordered 25 more chicks!!!
You could have a point about white egg layers although nutritionally there is no difference between eggs with different colored shells. I think part of the problem with selling Leghorns is that they are high strung and flighty (mine always screamed bloody murder whenever I handled them) and most people want docile breeds (including myself, which is why I no longer have Leghorns). It's the reason I suggested Austra Whites as opposed to Leghorns. California Greys or California Whites would be a good alternative as well. It's unfortunate that there doesn't seem to be hatcheries in Canada that sells these birds.
