Hello, i have a roughly 7 month old pekin chicken, just started laying 10-12 days ago, she lay and egg every day after laying she would come back out of nestbox. she has been in the nestbox now for roughly 4 days and no eggs ( she has been noisy last 2 mornings like she is trying to lay) i thought possible broodines but would she be trying to lay still??? singing her egg song but no eggs, she will only come out of nestbox if i take her out. she does not look sick ( no ruffled feathers or panting etc...). any idea??????
