My hens (4, 2 RIR, 1 Australorp, and 1 BO) are over 6 months old and still no eggs. Comb/wattle been developed (the RIR and Australorp) for maybe 2 months now. They sang the egg song a couple of times a few weeks back but still nothing. The days are getting quite short here but the Country store guy said first year layers may not be as affected by the shortened days... I gave up hope at this point.... Maybe they fly over the fence to lay the eggs in the neighbors! Very disappointed in them!
