This spring I bought 2 Narragansett Toms and 3 Narragansett Hens along with 16 of there eggs to hatch. I hatch the eggs and got 7. 3 of the chicks are yellow and the rest are brown. I though maybe the previous owner forgot to tell me he had some white turkeys too and he cross breed them. So I was fine in assuming this. They all eat the same . Well I now have 25 eggs I collected myself from the Narragansett and they started to hatch so far 2 brown and another yellow/white one. Is that normal?
