Okay I have 27 little chicks and last weekend my brother in law was over and said he used to raise chickens (to eat). Mine are strictly egg/pet chickens. Heres what he said- "oh it looks like you have some meat chickens in the bunch". I was like HUH?! They are supposed to be large laying pullets. He continues, "well sometimes they get big really fast and then they are meat chickens, because they will just fall over and die from a heart attack from being so huge" What on earth is he talking about? I've never heard of that. Not to say it's not true. Thats what I'm asking. True or not true?
