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?
I have two chickens and I get approximately two eggs a day. Their food is like, I dunno, $20 a month? Probably not saving money on eggs but they're my pets so that's why I have them. (not eating them, obviously. Or any chickens for that matter.)
