I have a 3 year old buff silkie hen. She has been a good layer (for a silkie). She laid her last eggs in July. She went into her usual broody period. When she came out of the broodiness, she molted as usual, but has not started laying again. At first I attributed this to the extremely hot weather we were having in Houston, TX. However, it has cooled down in the past 3 weeks and she has not started laying again. Also, her appetite is a bit depressed and she does not forage around the yard as she once did. Her poop looks normal. Could she be depressed? She is an only chicken with a elderly feline for company. I really do not care about the eggs, just about her health. I have noticed bits of white flakes in the bottom of her coop tray with an occasional feather. I do not see any insects. Her feathers look healthy. I am trying to decide if I should take her to the bird vet. Any ideas? Thanks for any input!
