We are new to the quail adventure. hatched some jumbo brown 10 days ago and was wondering if these are really jumbo. The largest chick at 10 days weighs 83 grams down to 65 the smallest one. We paid outrages for the eggs but after seeing the few birds this man had in his basement we were amazed that 3 of his hens tipped the scales at over 20 ounces. Question is, are these good weights for this young of birds? Thanks for any info this is our first adventure.
