he literally says it himself, it's because of the breeding season— also, I live in a village where loads of people keep livestock and it's known during some periods their eggs are bigger, for some chicks, not only do the lay less during winter (which is the normal) their eggs are also like.. half a hand big
Depends on the chicken if they lay bigger or smaller eggs but since he turned into a chicken only recently I assume his body hadn't fully accustomed and matured internally his oviduct and chicken organs lol young chickens will lay smaller eggs usually. So maybe his body is laying bigger ones now the more he lays and gets experience and matured those specific organs. Also probably has to do with hormones too. He's been having sex dreams about Little A so the hormones are rampant he wants those eggs fertilized lol

I keep wondering why kendricks eggs are bigger like, is he becoming a hen that lays L size eggs or smth, and why now? Im intrigued
