Glad you're here !
A must have for your poultry is a FIRST AID KIT for any issues that would arise. (https://www.backyardchickens.com/threads/suggestions-for-a-first-aid-kit.1150128/)
It's definitely better to have it and not need it rather than need it and not have it.
Also, make sure your coop(s) have a proper amount of VENTILATION. (https://www.backyardchickens.com/ar...-there-and-cut-more-holes-in-your-coop.47774/) Your chickens will absolutely thank you for it!
One last thing, if you're into gardening, feel free to join this years SEED SWAP (https://www.backyardchickens.com/threads/seed-swap.1220129/)

Happy
