I was not using Optifine nor any texture packs, just the normal game (I like the default look). The more I think about it I believe that chickens spawned with baby zombies are being treated as hostile mobs and disappear with time when I believe they should be treated as a friendly mob (normal animal) and not disappear with time. I'm sure that on older editions they wouldn't disappear, I farm these chickens on occasion for feathers for arrows.
