The only concern about hatching later in the year is staying warm enough for winter in my opinion. I like to get mine off heat by September at the latest to acclimate them to the weather changing. That's just my opinion though so take that as a grain of salt
There are benefits to winter hatching and benefits to summer hatching
Summer pros:
Chicks run around more and don't need to be sheltered as long and frequently by the mother.
Cons: More predators and sometimes the hens cook eggs during hatching. Water bowls are desirable drowning places and hens may wean chicks too early (I had a pheonix who weaned her chick yesterday at about a week old because she doesn't need to keep him warm in the day)
Winter Pros: chicks begin laying earlier than spring chicks, hens are unlikely to accidentally cook eggs while setting, less predators
Cons: Chicks may not run around as often and require more frequent and longer warming sessions with mother. Falling in water can wearily Lear to frozen chicks
Welcome to BYC. I can't think of anything to add to the good points you have already received, other than fall chicks in cold climates may require more food to grow as quickly as spring/summer chicks, since they use more energy to keep warm. My broody hens have hatched chicks every month except December, and for all the reasons @JacinLarkwell mentioned, I have no preference as to what season they hatch.
