I think my silkie is retarded, like mentally disabled. Shes not scared of anything, not the dogs, not the cats, not me. I've seen her attack my largest dog, which is some sorta shepard-lab mix. She chooses horrible nesting spots, and shes failed to hatch eggs three times already. This last time I had her efforts tightly controlled and monitored, and still the eggs spoiled without developing. they were supposed to be hatching, but instead one has exploded with rancid nastiness with no sign of anything resembling a chick. I know her eggs are fertile, because her beau is a randy one, He mounts her numerous times a day when they are together. Also she lays sporadically. Some times a week will pass in between eggs, and some times she lays 3 or 4 in a week. She just seems to be lacking the instinctive faculties, and natural capabilities of all my other chickens. Some of these behavioral short comings, like her lack of fear, make her my favorite for several reasons, and I'd love to have her be a mom, but the only chick she ever hatched was strangled in a most unfortunate butt feather accident. I'm working on making an incubator now. I should be finished this week, I hope this will solve my dilemma.
