I know the feeling of wanting to help!! You need somebody like my Lacy girl! Posted this a couple of weeks ago:
All went well for six weeks when, one day, all of a sudden, Miss Silver started pecking her chicks whenever they got near her, totally confusing them...it made me almost cry! She didn't want to be a mommy anymore!! Off to one side was Lacy, my GLW, observing this horrible act of nature and she began to slowly, hour by hour, get nearer to the two chicks, calling them softly like a mother hen. She would find bugs and worms for them and, finally, they started to respond and come running to see what goodies she had found. By the next day, they were following Lacy around like she was their mother and Lacy was basking in her new found motherhood! That night she tucked the two little ones under her wings on the roost and that's where they slept every night until they were too daggone big to fit under her anymore.
Lacy was not broody when the two chicks were with Miss Silver. I don't know what made her take over the mothering. Has anybody else had that happen?
