I need 3 more hens for my flock of 7 - I ended up with 2 roosters after the farmer at the NC State Fair swore he was giving me a pullet! My girls are getting "abused" so to say..... So, I found a place near by that is selling 3 day old chicks that have been sexed. So, since I have a mama and one baby that hatched about 3 days ago - I thought I could sneak in at night and stuff 3 more (of the same age) under her..... she'd wake up and hopefully not suddenly have learned to count! She has been a fantastic mama so far - very cool to watch. Is this possible? Highly possible or minimally? Thanks.
