Hello and welcome to BYC!
Oh absolutely! Trauma will clamp those eggs right off. If a hen is not comfortable laying, she won't. Laying leaves them vulnerable and she may be nervous about laying. She still may be healing internally. She may have sustained enough damage it may take her quite a while to get back in the groove.
Does she seem ok otherwise? You might try a ticking clock in the coop, maybe play a radio during the day only set to something quiet. I have had wonderful luck with both of these on stressed out birds. Also you might keep fake eggs in the nest box and hang curtains in the front of the boxes. This gives the hens a sense of privacy and security.
Good luck with your girl and I hope she gets back to laying soon!!
