Yeah it's pretty subjective, I use Cave-Born egg descriptions that I see in caves every 5-minute mark (plus a refresh or two to see which eggs replace the taken ones), excluding at the hour mark, because it seems that the 5-minute mark doesn't work well there as the server is preparing new eggs to cycle. Also, some eggs are actually repeated through the cycle within an hour, adding the complexity.

I can't possible gather data of many users on their breeding success rates, so I go with Cave-Born rarity as my guide, usually to distinguish Very Common, Common, and Uncommon.

Also, idk how market works, Chicken is at 5400 a very high price, yet I get them more often than other Rares (which means I almost never got other Rares lol)
