i have nine hen Salmon Favoralles that are now 6 months old and no eggs yet?? Should I do something to encourage laying? Also, I have an automatic door on the coop and they have all gone in every night. Recently, some are not going in and the door locks them out. I go out and put them in, but what would cause them to stop going in the coop before the door shuts? Thanks for the help! I just love my girls!
