I have 7 older ladies, 6 8 week old chicks i think 4 are roos and 2 are girls not sure yet. and 1 large 2 year old roo.. I put the 8 week olds in with the 7 older ladies and the girls the older ones keep picking and pecking on then. Every time one goes near them the older ladies chase the 8 week now 9 week olds around peck at them and pick on them. My question is this will this stop? as they get older. I mean they wont even let them in the coop sometimes.. they chase them out. please let me know..
