I have raised both heritage and commercial turkeys. they have slightly different needs and are a joy to raise whether its for your table or as pets. (Don't name them if they are for your table ;-) )
For heritage birds.
Breeding season here doesn't kick off until April.
I keep mine in a brooder tote for a few days until I'm confident they are eating and drinking properly, then I transfer them to an outdoor brooder coop with a heat lamp. At 2 weeks old I open the hatch door and cover it with mesh during the day so that they can get accustomed to seeing outdoors. They love to sunbathe in front of the door.
From about 3 or 4 days I pick fresh grass and cut it up into tiny clippings for them as a treat. They go nuts over it!
At 3 weeks old I open the hatch door for them to access their own run.
By 2 to 3 weeks old they are already making their way up to the roost perches 3 feet up. I have a long tree for a perch but they prefer the flat 2x3 timber as a perch.
Once I am confident they come to me when called I take them out for a walk about in the morning, before feeding them is best otherwise they have no interest in coming back in ;-)
I feed them turkey starter until 6 weeks old then switch to turkey grower which I feed to all of my adult turkeys, chickens and guineas. (layers/breeders are offered crushed oyster shell free choice)
I've previously never lost poults and they grow up to be strong and very hardy birds as well as very friendly and managable.
This year however I raised 25 poults with 15 chicken chicks. This year we had a coccidiosis outbreak and lost 11 poults before we had it under control. The chicks never developed symptoms. We were lucky it wasnt Blackhead.
Last year I raised 6 commercial (broad breasted) turkeys, we can only buy poults at 2 -4 weeks old here.
They grew big fast! I called them all Bernard (even the girls hahaha!) They slept on the ground at night and were very active during the day as 4 heritage Royal Palm poults were raised with them. The Bernards were very inquisitive and followed us everywhere.
We raised them to 18 weeks. The largest tom weighed in at 35lbs dressed. The smallest hen weighed in at 26lbs.
We lost one at 16weeks when we found him on his back - probably a heart attack. I was so upset to lose one at that size.
The commercial birds eat A LOT! and drink a lot too.
I hope you enjoy raising turkeys....they are a hoot!
