I learned a good lesson hatching bobs.
#1 they need food right away.. . not just crumbles but, CRUMBLES you'll have to put the crumbles in a blender or manually crush them in order for the food to be small enough. As soon as they pop, pop them in the booder
#2 don't put the feed in a feeder but sprinke the dust around on the papertowels you have as bedding in your brooder for the first couple of days so they can easily find the food.
Bobs sometimes hatch looking wacky but they will straighten up.. most do anyways... Just be sure they have access to food or you will be doing the all night wet mash/yoguart syringe thing every few hours like I did for not being smart enough to ask on here. Im glad you are. Good Luck.
