are you saying the worms are as long as she is long? If so, then no, she prob wouldn't even try to eat them and I wouldn't think it safe to feed those larger silkies to a 3month old.
what i have heard is not to feed your young chams worms quite yet.. it may become partial to them and stop eating crickets.. if this happens it will be a task to convert it back to crickets as adaily supliment...i would honestly hold off on the worms until your baby is 5-6 months.. maybe more..
