I understand the fat can be used for numerous things, but also haven't researched it yet...
Bones are more brittle than what you expect because even though they are big birds they are still only 8-10 week olds and the bones haven't 'hardened' yet, or calcified. Growing bones are generally porous and easily broken. The faster the growth the less time the bone has to fill in the pores. I don't know that adding calcium could even keep up with the growth rate of the average broiler. Most folks just try to balance it so the growth rate is as high as possible without causing an extreme issue with the bird's mobility which would force early culling.
they have soaked since processing Friday afternoon, I am thinking about bagging freezing today, it says 48 hours is best to wait until freezing.
I guess I could shrink bag them today refrigerate and then add them to the freezer tonight. same thing as 48 hours right?
about the shrink bags...
do I add any water in the bags at all? there are no instructions, I have stickers to put on the slits. and what temp hot water?
