i got 25 roosters off a lady for butchering. they are 8weeks and they feel way to thin, breast bones very prominant and they have very thin "drum sticks". i was wondering if i feed them a bunch of broiler feed if i can get them up to size with in a few weeks or is this a lost couse? any advise would be great. i have never raised chickens before but got a lot of great info off here and it seems like i might be out of luck oh and they are barred rock, road island reds, jersy giant and buff orpington THANKS!!!
