Yeah, eggs are great. A while ago I saw an old lady (over hundred) talking about eating every morning a row egg, what apparantly kept her healthy for so long.
However if you see the bigger picture:
In Europe are currently breed two kind of chickens, one for eggs and the other for meat production. For the last one will be used male and female chickens. But for egg production only female chickens are suitable.
Worldwide about 2.5 billion chickens annually are killed either by gas or by a machine, which cuts the birds alive.
Oh dear !
