well we "accidentaly" got some cornish rocks at tsc. we are new to chicks and even thought we said we wanted pet/layers the guy let us walk right out with two. my dh will have no problem serving them up for dinner! anyway they are almost 4 weeks,when can they go out? i thought i read as early as 4 weeks,what does the temp have to be? and since we will probably butcher them at 8 weeks (right?) can i just let them eat all they want?
