Often shortened to 鶏卵 (けいらん) in formal or written contexts.
In Japanese, 鶏の卵 specifically means chicken eggs. For other bird eggs (e.g., duck, quail), use 鴨の卵 (kamo no tamago), うずらの卵 (uzura no tamago), etc. The default assumption in Japan is that '卵' refers to chicken eggs unless specified otherwise.
If the context might confuse 鶏の卵 with other types of eggs (e.g., in a recipe or grocery store), explicitly state 鶏の卵 to avoid ambiguity.
鶏 (niwatori, 'chicken') + の (possessive particle) + 卵 (tamago, 'egg'). The compound refers specifically to eggs laid by chickens, as opposed to eggs from other birds.
While 鶏の卵 is the literal phrase, 鶏卵 (けいらん) is more commonly used in formal writing or when referring to eggs in bulk (e.g., in agriculture or food industry). In everyday speech, 卵 alone is sufficient unless differentiation from other types of eggs is needed.
