i introduced some silkys to my flock at about 3months old and now that they are almost 4months old 2 of my red sexlink hens have started sitting on them spreading there wings over them and the 2 hens are actually helping keep the chicks under the wings by overlapping there wings its funny becouse at 4month the silkys are basicly adults but i think since my hens have never seen a silky the think the fluffy little things are baby chicks they still cheap instead of cluck too
