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.
