I have 5 seven month old araucana(or EE) and they eat massive amounts of pine shavings and lots of other non-food material. They have free choice layer crumble as well as an oatmeal/ crumble mash I make for one with crossed beak. They eat so much pine shavings that some of their poo has "saw dust" in it! They also got at some pink foam insulation and were picking and swallowing it. I had removed shavings and tried newspaper, but they eat that too, also it is not as warm as shavings for winter. I removed the straw from nest boxes and just using shavings. I have (think it's a) rooster with pendulous crop from eating long grass so I am most worried about straw. At least the pine shavings pass! I had given them grit, but chicken with pendulous crop filled up too much on it so I removed. Main diet is layer crumble but Should be stones in run if they need. Has anyone experience with this? What will happen to the insulation they ate? How can I make them stop? Any other bedding options? They do have an outdoor run with dirt which I can not control. Crop impaction is big concern. Bird with large crop has been like that for over 4 months, skinny but otherwise healthy and poops. First time poster, hope i did it right, this is such a great site!! Thank you for your help!
