Hi y'all, Might be a stupid question. My 4 plus weeek old RIR and BSL chicks feel skinny to me. They have food 24/7 Dumar chick starter and plain yogurt a couple of times. They are VERY active in the booder and are flying freeks! Is this just teenage growth spurts? They poop regular and everything seems normal. They just feel boney on the chest when I hold them. I have never had chickens befoe so any input is appreciated. Love this site!
