I just started and have not yet had to take my birds through the winter but I decided not to try to get new chicks after a mid August hatch batch. That group will be three months old before we get a hard freeze and will go into an insulated coop in their own section where I will be able to put in a heat lamp if needed.
That may be overkill but why take the chance after I've used all of this time, energy, and organic feed to get them to that point?
I am going to jump on the first opportunity to order from the hatcheries this Fall to make sure I get what I want. Last year I had to settle for some things, like straight runs, that I didn't really want to get and was unable to find some breeds available.
My plan is to arrange for a hatch date in March and put them in the greenhouse which I will be opening up for my plant starts at that time. That way I won't be spending extra heat such as I would if they were in the barn where I have the present batch and won't have to bring them in the house where they will be stirring up dust.
I won't have eggs until September, but my other batches will be producing by mid to late Winter with supplemental light.
