I went out tonight to put the chickens to bed. Blind Tiny was up on her waterer so I put her down to put her on her roost. She started pecking the ground and eating pine shavings! I put her at her food (like I had to do last night when she acted like she was starting) and she started choking on her food. She had her beak wide open and was making a honking noise. I got her out of the house and started putting water down her throat. I brought her into the house and tried to look down her throat but she wouldn't let me hold her beak open. I took her back outside thinking she just ate to fast and she started eating and choking again. I had to put her in a a cat carrier to keep her from eating. WHAT'S GOING ON!!!???
