I have a mixed flock with 4 BR, 4 EE, 5 RIR, and 19 RSL. I know the EE's are putting out eggs regularly, and the BR and RIR are contributing pretty well too. We have been getting 13+ eggs a day for the past week. The RSL are 25 weeks old. I only see 3-4 of them with larger red combs and waddles. I thought they were supposed to be "egg laying machines". Everybody is getting flock raiser with oyster shell in a separate bowl. They all free range from sunup to sundown. Is there something else I need to be adding for the RSL or are they just developing slower for some reason? Even my roosters seem to notice the difference. I rarely see them mount one of the RSL girls.
