Sorry if this has been covered somewhere else and I missed it, I intend to research it more after I get back from church. I have one girl that is bullying, but she's also eating feathers. She's in time out now, and has been for 2 days... wanted to try getting her away from the flock and re-introducing her to possibly affect pecking order. Yesterday she laid two eggs in 15 hours, and that started me wondering if she may have some sort of nutritional deficiency..laying eggs that quickly has to be fairly taxing on a chicken. I feed a 17% gamecock conditioner and keep grit as well as oyster shell out on the run all the time...they usually free range three or four hours a day as well. I'm just wondering if I should consider putting some supplemental vitamins in the water to help with the feather eating and pecking. Thanks all and God bless.
