I have 7 month old large production red sex links. Big girls now. Started laying eggs about 1 month ago. 7 pullets. I'm averaging 3-4/day. Eggs are medium size. The egg size concerns me. Will the hens lay bigger eggs eventually? They are Rhode Island/New Hampshire crosses. Very friendly and vocal. Most know their name. I live in S FL so the weather is usually warm. I also have Barred Rocks, Buff Orphingtons, and multiple yellow sex link chicks.
