Hi, We have two new additions to our coop. One of them is a Buff Orpington and is supposedly 9 months old and laying. The other is a Favorelle and has laid two eggs so far. The problem is that it has been a week since we got them and the Buff has not laid an egg yet. Her face seems red enough and her comb and waddles are large and red. Is there an adjustment period? Do they just stop laying if they are moved to a new home? How long should I expect to wait for her to lay again before contacting the seller? Did I receive an older hen? Thank you!!
