cornish chickens

Question
hi  i  have cornish chicks that are four weeks old and are having leg problem i started them on 20% starter grower which i was told to use what can i do to help them i plan to butche them in about three weeks please help.  

Answer
cornish birds almost always have leg problems. this is because they are breed just for butchering, and they are done in at a young age so their legs don't grow strong. make sure that they can't jump off of anything because their legs can break very easly.
