Hello all, I have 6 older laying hens and a roo in a coop and inside my run in a separate coop are the newer (10 of them) chickens that came to me on May 30th.. so they are about 13 weeks old.. they have all been able to see each other while separated.. Yesterday I let them out into the big run with the others as they are getting so big and all has gone well.. my question is will the layer feed hurt the younger ones if they spot it and eat it? I am trying to keep the feed separate, but it is not 100% guarantee that they will not get into the older girls feed... I realize they should be about 18 weeks before going on layer feed.... thanks all.....
