Robby even went out of his way to help me figure out what went wrong with my first attempt of raising a true Jumbo bird. I have a new line of eggs coming from James Marie Farm and I'm sure I'll get even better results with my next hatch.
That's very interesting, i actually thought it was the opposite.
Let me share my experience.
I hatched some jumbo quail eggs (that were advertised as growing to 350grams) and they were doing great, i was weighing the largest chicks daily and they were putting on excellent weight up to 3-4 weeks, they were getting too messy and smelly so i took them outside daily (outside temps were approx 5C) and bringing them back in at night.
After the few days of taking them outside i was disappointed to find out they hadn't put on any weight at all so hoping for larger birds (these will be used to breeding) i thought I'd put up with the smell for a bit longer and sure enough they started putting on weight again but suddenly stopped after a few days or so and that's about the time the males started crowing (4-5 weeks).
The temp indoors was about 20-23C but it was definitely hotter than that in their cardboard box as it was covered with a fine mesh, they were eating approximately 500grams a day between 14 birds.
The hens are still growing (at least some of them) but the biggest male is approximately 250grams and i don't think they will grow any bigger.
