Of my flock of 6 (Barred Rocks, NH Reds, and Wyandottes) hatched around 4/1/16, I'm pretty sure 3 of 6 are laying and one looks close in terms of comb/wattle development and the other two do not look very red in face yet. So you're not alone!! I'm thanking my lucky stars at least a few are cooperating so I don't have to buy too many eggs this winter! Hopefully they'll lay longer later in life since they appear to be taking a pass over the winter...
