Historically, care is taken so that there is no item or block named 'X' that is related to a 'Yish X' or 'Zish X'. For example:

• Wheat seeds were simply seeds until 1.13, despite melon, pumpkin, etc. seeds existing
• Turtle scutes were simply scutes until 1.20.4, when armadillo scutes were added

However, this consideration has not been taken into account for eggs; simply eggs (dropped by chickens) exist, along with dragon eggs, turtle eggs, and sniffer eggs. I believe this issue causes confusion for users as 'egg' can refer to both a specific item and a category of items.
