To lay or not to lay?

Hi there

I am hoping someone may have come across something similar. I have a black rock hen, in her first year, who has been laying probably 6 days out of 7 since I had her (in April). For the last couple of weeks (notably since the days are getting shorter) each time she has laid it has been quite early at about 0830. The last 2 days she has been going into the nesting box at the same sort of time  but not laid any eggs.

She looks as though she is in lay (bright red wattles etc) and appears in good health and acting normally in every other way, with a good appetite etc. I have picked her up and gently felt underneath but I can't feel anything hard/egg shaped but as I am new to this I compared her to my other hen and they appear the same (the other hen is laying normally).

This doesn't seem right to me even if she appears well in other respects & I am bit worried  - does any one have any ideas?

Many thanks in advance

Helen

I think she would be in distress all the time if she had an egg stuck.

Mine are starting to go a little inconsistant now with their laying, I have an ex bat who has never laid, prob just goes and breaks wind but she will as yours are doing sit on the nest for 20 mins then walk out.
I often think like us we are creatures of habit, thats what the brain tells them to do so they do it.
I agree with Aunty, I would of thought if there was a blockage she would show signs of stress by now.
