I have six chicks. Three are Reds and three are White Leghorns. I assume. Purchased them at Tractor Supply. All but one have bright yellow orange feet, but one has brownish feet and a speck of blood on one toe. I figure maybe she was pecked when they were reaching for food, but the different color has me concerned. She walks fine and is the first the hop onto my hand and listen to me talk. Am I overreacting?
