I can say I'm ready for spring, but we barely had winter so far. About a week of real cold, a bit of snow twice. But for the ridiculously short days you would've have known it was mid-winter here!
Oh you should! She sounds like a fantastic layer and if she passes that trait on to her chicks... Yes!
She'll probably continue laying through summer and then take fall/winter off to molt and catch a break. My Sussex hen starting laying in August (2015) and only took the last 2 winters off finally.
Here is the same with winter non-existence, but I hope we won't have it at all. Snowed few times and melted the same day.
We should be getting a few more hens this spring, but I wil try to get something that goes broody since I have never hatched anything and I have chickens since I know of myself!
