The birds I have are extremely hardy. We get -30,lots of wind and snow. Summer it can get hot and the birds have never shown any discomfort. One of my hens laid over 20 eggs before letting her go broody, my other two hens each laid 14 and 12 before turning them loose. I have never had a Tom show any kind of aggression except to each other during the spring.
One thing you cannot confuse is the commercial turkey poult with a heritage breed. The poults I have hatched for me behave like a wild game bird. They will hide from you if they get out of the brooder. They are very smart making chicken chicks look really dumb.
My toms are friendly, they will gather around me but won't let me touch them. The hens seem a little more cautious around me. However I have seen people pack them around like pets. It just depends on how you raise and interact with them. My birds free range and take care of themselves for the most part.
They are very curious birds and entertaining to watch.
I have not butchered any of mine so on taste I can't help. For weight, I am estimating, 20-25 lbs for toms and 12-15 for hens.
I shipped some eggs earlier but until I hear how the hatch went,I can't tell how they shipped. My birds were obtained as adults. I do know that the hens have large broods every year and free range poults encounter lots of mishaps. The poults that are hatched for me do very well,I believe I have lost only 3 in the last few years.
I also have my birds with chickens,guineas and peafowl.
