Hello! A friend asked me for some advice on her chickens and I'd love to get your help. Can you please tell me how old you'd guess the chickens are? There's a lavender, a silkie and an EE. The silkie has since turned out to be a roo, but we're still trying to figure the ages. These are the only pics she had on her phone to show me, and they are from when she first got the chickens. Thanks so much!
