Hi! I’m new to quakers as well and just got a 3 1/2 year old Quaker last Sunday so I'm learning about them too! So far he’s very sweet, but he’s can get loud, especially when my other birds are being noisy while he’s trying to nap. The only thing I can think of right now that you need to know is they need a good diet to avoid fatty liver disease, my Quaker has been eating Higgin’s Vita Seed for bigger birds which he likes but I haven’t confirmed if it’s good for him yet, pellets are a good idea to try, and make sure you provide fresh fruit and veggies regularly! If I think of anything else I’ll let you know, good luck!
