I grew up on a dairy farm in NE Ohio and when I was there and in my early teens I raised baby wild rabbits that were in the nests and who knew where momma was after the silage chopper went over. So my dad and the guys on the farm would put the babes in their shirts and bring them home to me. Some with their eyes still closed. Raised them on Carnation milk and a very tiny bottle. Let them get 1/2 grow and eating clover and lettuce then let them loose in Cleveland in the ravines. Didn' t want them hunted. Did that for 10 years, even when I moved out on my own. Also raised ducks from eggs(nest found the same way as the rabbits) with a chicken hatching them. 11 0f 12 eggs hatched, Poor hen became so neurotic after the whole deal. I put a tub of water out in the yard when they had real feathers and the hen went nuts because the ducks took to the water as ducks do, but, chickens can' t swim. She hollered and hollered at them. After a few days she accepted her " chicks" can swim. Then came time to fly. She hollered and hollered at them cuz chickens only fly a few feet and not very high. Then she again accepted her" chicks" could fly. Then fall came, and they flew back to our pond for a few days and then migrated on. They returned every year the to yard and then the pond for 7 years. Each the number returning dwindled til the 7 th year 3 came back. On the 8 th year none. The hen was never the same again. And neither was I.
