Thank you and glad that you liked the photo's my friend.
I feel sad in saying this, but there are many predator birds and animals over here that needs to eat in winter.
We have lost 2 guinea fowl nests of 12 keets each to predators. 24 babies just disappeared over a few days time.
I think you need to careful with the oak tree acorns and first do a bit more research about eating them first. There's a lot of information on Google.
Blessings!
