I'm not sure they'd wait, but eggs may be few and far between. They should be laying though. Have you taken a look through the yard, and under stuff? Sometimes my girls send me on an egg hunt.
Quick story related to egg hunts...
Two weeks ago, I was putting the girls to bed (locking up the hen house and coop) and when I counted, my BO, Lovey was nowhere to be seen. My husband and kids all came out and we searched everywhere. I was so upset since it was almost dark, and we have tons of raccoons. All of a sudden my oldest son yells, "MOM! I found her!" Sure enough there was Lovey, under the small propane tank, which is like a big one on it's side, pretty as you please....on 19 (YES, I know-what the heck???) eggs. They were all different colors and sizes so I knew ALL the girls were in cahoots, SO we emptied her cache, and put her in the hen house. 2 weeks later, all the girls still roam over to the propane tank looking for the eggs, clucking away at each other.
Little creeps.
