Two of my 3 RIR's started laying this weekend at 24 weeks! I went out to feed them on sat. morning and there it was, right in the nesting box where it was supposed to be. The funny thing was that all 3 of them were surrounding it looking at it and making all kinds of noise. Then the other one layed her first one that same day...we got 4 altogether this weekend and another one this morning! yippee! Ironically, the older one (26 weeks) hasn't shown any interest in laying and doesn't even have a red comb yet.
