Here goes nothing:
Peter (as in Peter rabbit, going off of this alone you could tack on Flopsy, Mopsy, and Cottontail), (Miffy, Hazel, and Lola are also bunnies from books/movies), Peep, Jellybean, (or other candy names, i.e. Rolo, Hershey, Kit and Kat), April, Daisy, Tulip, Rose, Lily, Sunny, Lavender, Daffodil, Meadow, Violet, Blossom, Azelea, Petunia, Iris, Petal, Sage (female or male), Forrest, Creek, Orchid, Aviva, Cedar, Reed, Dawn, Lake, River, Leif, Honey, Birch, Everett, Breeze, Moss, Calla, Ash, Dahlia, Ivy, Hunter, Amaryllis, Sterling, Ash, and Bluebell.
Or even color names that remind you of bright Easter eggs and flowers (some are repeats of flower names LOL):
Indigo, Coral, Azul, Violet, Rose, Azure (or Azura), Hazel, Lilac, Cerulean, Roux, Olive, Cyan, Scarlet (or Scarlett), Aurelia, Topaz, Sage, Morado, Beryl, Jade, Lavender, Emerald, Auburn, Blue, Ivory, Red, Clementine, Sapphire, Pink, Ebony, Mazarin, Green, Mauve, Alba, Saffron, Viridian, Fuschia, Ruby, or Kelly.
Apparently Easter is a boy's name, too. I've never met anyone named Easter, but it's a cool name!
Some more Easter/Spring inspired name meanings are:
Caldwell: English boy name meaning “from the cold spring”
Attwell: English boy name meaning “lives by the spring”

Atherton - English name meaning "from the town by a spring"

Hope this helps! Being an avid writer in my spare time, I often compile lists just like this (if not longer) just to pick a character's name (it has to fit just right!). If you need more names I can go another round later, but hopefully this is enough to name all your adorable babies. Congratulations!
