All of mine are fairly new layers, 6 weeks or less, and initially the first couple weeks it was pretty sporadic as to time of day but predominantly the first half of the day. Now they seem to be more regular and earlier in the day. Today, for example, 4/5 laid....first three in quick succession by 9am, then the last egg about 11am ( she is also my newest layer by about a week). I have six hens, 2 BO's, 1 BR, 2 EE's, and 1 white leghorn/RIR mutt.
