Advantages of half peanuts arising from my point of view, especially in winter for the birds when they can take such a big piece of the same with the nest with only a hint of the feeding site, rather than eating the same amount in the cold spot or to fly dozens of times. In particular, chickadees seem this (all year) to handle so. Once the houses are refilled, the titmice come and take the peanuts usually solitary them. The other species of birds, these but usually patronize locally.
The seeds also have externally a top quality, where it is in my view almost entirely by half, not all, peanut kernels. Well - insbesonderer with balcony feeding - and of course, that there remain no shell residues.
Conclusion: Although "My" City birds eat - even with obvious pleasure - throughout the day, all the foods offered at that peanuts are but clearly all the rage among the species and because of their fat content, especially in winter probably indispensable. Therefore, a strong buy recommendation - for the whole year!
