i just did this a couple hours ago.same hen last yr didnt have too much trouble adjusting,this year i dont think its going to work,i'll check in another hour
my BA hatched 3 eggs,then like 4 days later i bought 2 buff brahmas and a dark brahma that were a couple days old i figured,,the 2 buffs she accepted as soon as i put them by her they ran right under her.the dark she didnt want anything to do with for some strange reason.So yes and no i guess??
