My chickens are thin. WHY? They get plenty of food (TSC and cracked corn..plenty of both) all day as well as water. During the day they are free range as well. When we have killed one for the table, there are no signs of worms anywhere. A few have sniffles. I have had a couple of dead ones in the last couple of months which I thought was probably from cold, rainy, windy days...all of that snow up in the NE we get as rain on the Easterh Shore of VA. They also get granite grit, oyster shell and the fresh vegetable scraps each day. ( leftover from 2 people, so not a ton) Any ideas why they are so thin????
