Ok so my ladies have now decided to stop laying for days now its been two weeks since ive brought them home and in 2 weeks ive only had 4 eggs and I havent had any in 3 days ! whats the deal ? also is it true that they dont start laying until there comb is red ? because two of my ladies have a beige comb and no wadle i mean its starting to turn a hint of red near her skull but is it too early for those one to start laying ?
