RIR gender 5 weeks.

[Sloane Chickens]

I'm not sure. If they look healthy and behave normally, then they are probably just very slow growing. They should always have quality feed always available at that age, and it must be high protein, like 20 to 22%. The feed should contain all of the vitamins and minerals necessary.

If they have that, then I would not worry at this point, but I would keep watch on them.

These are too young to say anything about gender. Feather sexing will not work unless it is bred for, as in Amberlinks. You will have to wait until they are bigger and mostly feathered out, which will be late for these ones. Then you start judging by combs and wattles, color and size.

Yep they have that re: feed.
I’ll definitely monitor them. Thank you!
