I do not understand the mathematics behind the dilemma. I'm assuming only the firts chicks cost money, because down the line they will breed.
But feeding them, housing them - vitamins and doctoring costs a lot of money.
So anyone with couple or more chickens - how much does it cost to have them on the table? And realistically how many eggs do you get?
So it all comes down to what the chicken's eat.
I'm assuming with mealworms added to corn / legumes / other seeds should be a balanced diet. And if they are relatively free they can go hunting too.
Do meat chickens still lay eggs, just not as many?
