My heart is broken, I never wanted chickens they were my husbands idea/hobby and I thought he was nuts. 2 years ago we got our first 5 girls (red/black sexlink & barred rock) it's fun watching them grow and develop their own personalities. A year later we got 4 silkie chicks 3 of which ended up being roosters we couldn't keep due to living within city limits. We did everything we knew to make her apart of the flock they just never accepted her. So when we got our next to hens (buff & Americana) we put them together hoping they would become their own group. Well they were fine then we started noticing the older they got the more they started picking on our silkie as well. She learned to stay out of their way. She was broody most the time and they would get beside her in the nesting box and lay eggs she slept next to them. We never expected to find her dead today. My heart is in pieces she loved us and we let her down. It makes angry at the other girls. I never imagined I'd be so hurt over losing a chicken but she was such a sweetheart.I was thinking about bringing her inside crazy enough..
My vet always ends our visits with a reminder to use vitamins for the chickens. I feed Rooster Booster, Multi-Worm Booster, and Poly-Vi-Sol no iron liquid vitamins to our chickens. I also have liquid vitamin E oil refrigerated and E capsules on hand if I momentarily run out of Poly-Vi-Sol. I also sprinkle a very tiny bit of Selenium powder into their organic cooked brown rice along with added Brewer's Yeast and Bee Pollen. Some of it goes to waste but I'd rather it be available then not offered at all. Extra vitamins may or may not be your Silkie's haunches problem since that could be a symptom of any number of maladies -- but vitamins should always be prudently supplemented in any chicken's diet.
How often do you give vitamins I just have two that run the back yard and eat shiebird food when they want I give oyster shell and scratch
