My CXs are doing fine, at 17 weeks old. Instead of getting more crippled as they age, they appear to be getting stronger and more agile; especially my CX cockerel. Anyhow, the farmer that gave them to me was up here the other day and he was shocked. He said the pullets should be laying any day now. I know that they are quite developed in the comb and wattle dept., but I thought they'd be some of the last to lay. Anyone have any idea at what age a CX would start laying? He tells me these are "Cobb on Cobb" birds.
