RIR @ 6 months old. Laying on side with one leg seeming not functioning. No signs of trauma. As stated in subject - know that some moldy/runny in the bag carrots were put out in compost just yesterday. This morning things seemed normal. Noon found her in barn on her side. Checked around and found the carrots. Haven't seen poo yet. On the way to store for yogurt to mix with her feed. She's in the bedroom in a sling that lets both feet dangle atm and seems content. Coop is cinder block building with straw over wooden floor. All other birds look fine so far. Don't know how many would have eaten the carrots but if things were like normal most got their beaks in the party.
