This is my first post, so here goes...
We raise Narragansett turkeys at 5,700 feet altitude. We started incubating several years ago, with some older Kuhl units I bought used. We recently purchased a Grumbach digital unit.
Our most recent attempt was with a small batch of 14 eggs from our breeder flock.
Day 1 thru 25 = 38.3c and 40% humidity. Weight loss was calculated at 13% by day 25. When the eggs went into hatch mode, we cut the temp to 37.0c and raised humidity to 75%.;
5 good poults.
1 partially pipped, dead in shell, poult was too large for shell.
6 developed poults, dead in shell with excess liquid and yolk sacks not absorbed into belly.
Next batch goes in tomorrow. Looking to cut temperature to 37.5c and humidity down to 35%. and increasing weight loss to 15%
