On Wednesday while I was at work and my husband at home a flock of crows flew low over the house and panicked my chickens who were loose in the backyard. He said they ran around and flew and retreated into the line of Forsythia bushes that border one side of the fence. He told me one of them was limping. When I came home I found Rita lying down. I got her up and she was limping badly. I took her back to work and radiographs showed a fractured femur close to the pelvic bone. We had to put her to sleep. I am now very concerned about the bone health of my birds. I did not see what happened this could have been a warranted fracture if she really slammed into something or it could be poor bone health. I feed Purina Layena free choice. Pulled the tag of the bottom of the bag. Ingredients list is very vague much like poor quality dog food. First igredient processed grain by products, grain products, plant protein products etc. Can anyone suggest a superior product. Anybody feed Countryside Organics? It is a soy free product that explicitly lists its ingredients. Field peas first, corn, oats wheat, Ca Carbonate, fishmeal, alfafla meal, flaxseed, rice bran, kelp and more.
