Actually chicken meat isn't that much healthier than pig or cow. I highly recommend this talk by Dr Steven Greer on the subject of consumption of ALL animal products:

And a little side note you may not be aware of -- the dairy and egg industries are the most cruel. The baby calves are taken from their mums and either killed for veil if male or to be grown into another dairy cow to be rapped in order to produce milk, to repeat the cycle. In the egg industry baby male chicks are killed upon birth because they can't lay eggs.
