I put my nine 3-4 wk olds in with my two older hens yesterday. This is the batch that included that runt. And also what I think is an absolutely gorgeous hen.
Anyway, the sudden change only got me one egg overnight. Up til now I have been getting 2-3 a day. Those two have been excellent layers.
But, since I'm sure at least a few of the younger ones took over the hens' favorite laying spot, one actually went into the box I've had in there to lay an egg.
They've been using the box... I see feathers in there and the wood chips moved around... but have never used it for laying before.
Everybody seems to be getting along.
