Is Scab formation on Day 13 Post FUE normal ? Its my day 13 post FUE (3000 grafts) and i have the following questions: (photos)

a. The grafts were removed between 11-1 pm in the morning and placed between 2-6 pm, is this period enough for the grafts to remain viable? b. How long does it take for the grafts to get firmly placed? c. I did not wash my hair for 8 days and post 8 days have been applying shampoo foam and let water trickle over it from the back of the head to the front. Is this correct? d.I just touched a few dangling scabs and the hair came out along with the scabs. Have i uprooted the graft from the root?
