I currently have 6 laying hens. 3 of them are just over 2 years old and the other 3 are just over 1. However, none of them have yet to molt. A couple times they have all looked a little rough but then no molt. Is this normal? The 3 oldest are a Red Sex linked, Black Barred, and a White Leghorn. The younger 3 are Rhode Island Reds. Should a molt be coming soon? Less the Leghorn the others have been laying continuously since 9 months of age.
