You’re reading too much into it. The old traditions were of breaking the fast by eating meat and eggs, since eggs were easier and cheaper to get for many than meat. Since eggs are seen almost universally as a symbol for rebirth, they are a natural for Easter.
While other traditions colored eggs, they had their own rationales for doing so. The eastern Orthodox still dye their eggs red, as representative of Christ.
The Easter bunny origins are very Christian. The hare was a popular motif in medieval church art, as it was thought since ancient times that hares were hermaphrodites, so could reproduce without the loss of virginity, which led to an association with the Virgin Mary. Hares were a common motif in paintings of the Virgin and Christ Child.
So these modern practices are all acceptable extrapolations from the Bible, along with errors. And while it does not mention Lent, as such, the Bible has other references to fasting, and when it is appropriate, and also of Jesus fasting in the desert, for a length of 40 days, much as Lent.
How is that following Christ? Participating in pagan rituals?
Do you remember the 1st Commandment, written in stone?
