A study of the effect of normal environmental conditions on newly hatched chicks with the feather mutant described as "wiry" (Fiser et al., 1973) was carried out. The results indicated that the abnormality should be classified as a potential facultative lethal expressed after hatching.
针对正常环境条件对被描述为“刚硬”羽毛突变体的新孵化小鸡的影响进行了一项研究（菲泽等人，1973年）。结果表明，这种异常应归类为孵化后表现出的潜在兼性致死。
