Hi, I recently successfully introduced 2, 10 week old pullets (1 red sex link and 1 white leghorn) to my 20 week old flock of 2 pullets. (1 barred rock and 1 Rhode island red). I was very happy that they all live now happily in one coop. today my barred rock gave me her first egg (Happy day...) and now I have a problem I didn't foresee. As they all eat together the same food, do I give them all the layers food, or wait until all my pullets lay before changing food.
