Eggs Hatching - Small Issue
Featured Stories on BackYard Chickens
3 days should be ok. Shipped chicks spend 2 -3 days or more in transit.
I'd give them some chick electrolyte and have feed ready as soon as your get them out. When you put them in the brooder, make sure each one drinks. You may have to put their beak in the waterer to show them. Then peck you finger in the feed like a hen would peck to show them the food.
