I am new to raising chickens...I have 4 RIR and 3 Speckled Sussex (thanks BYC forum for informing me of that earlier today). I went out yesterday to see what my flock was into (I let them free range during daylight hours) and they were all eating the little GREEN Polk Salad Berries. Is that okay?? I was expecting them to want to eat them when they were purplish, but green? Really? My chickens are around 6 weeks old and growing beautifully, I would hate for this to make them sick. What is really strange is they haven't touched any of the blackberries that are still green too?? weird??? Any input would be great! Thanks!
