Hi, a buddy of mine bought some silver laced wyandotte hens and was told that they were 7 months of age and when questioned about the age she said they had hatched in May which puts them at 8 months. I'm thinking they are about 4 months of age but am no expert on wyandottes. Can anyone help with placing a close age on his birds? One other thing is 2 of them have slate colored legs and the rest are yellow legged, is that normal? Thanks for your help!
