3 months.
That's what I've heard, it's interesting that with some groups it comes up and with some it's doesn't. For example, I've had hatchery stock brahmas from a couple different places. From mcmurray the lights had the partridge patterned spots but the buffs didnt. From cackle both the lights and buffs did not have spots. Usually the chicks have shown it right away, the mcmurray lights were almost completely black while the cackle lights were a solid yellow.
I can try and get some pictures of them, though it doesn't make much of difference with this batch since they are all males anyway lol. There's one that I would consider "lighter" than the rest but not by much.
One of our other hens was setting on a couple eggs from our hens (before they shut off) and they would be either a pure buff, pure light, a combination of both as we had a light and buff rooster and light and buff hens. They are only a day old but they are completely yellow, no black on them. Since we had that light rooster in the mix, I'm not sure what we are going to end up with....since if I remember correctly, the buff over light would make sex links and light over buff would make lights but with yellow on them.
(I know the plural of bison is bison, (lol) but I just like it better with an “s”.)
