First, hard feathering and silkie feathering are separate genes, not opposite alleles. The opposite of silkie feathering is typically referred to as normal feathering or non-silkie feathering. As examples of the differences, game breeds typically have hard feathering while cochins and brahmas typically have soft feathering.
Silkie feathering, which is what you are really asking about, is recessive. Since you had silkie feathered chicks, the sizzle parent carries one copy of the gene for silkie feathering.
