Amelia/ectromelia in association with scoliosis in three commercial layer hens (Gallus gallus forma domestica).
Three wingless "healthy" pullet hens were serendipitously discovered at a grow-out facility for an egg-production ranch. Two of the birds were amelic and one was ectromelic. The defect in these chickens differs from the previously reported wingless mutations in that all three affected birds also had scoliosis. The birds also differed from previously reported scolitic mutant chickens in that they were wingless. Although the combination of amelia and scoliosis has been reported in humans, this is the first report of the combination in an animal species.
