i had a hen take missing, turn up a month later with 14 peepers, and they have been completely yard raised since then. i gave away 8 at 2 weeks, snake got 2 of the peeps, and i have 4 left now, 5 1/2 weeks old. momma hen went back to the roost at night when the chicks were 2 weeks old, the peeps got on lower a lower perch, until a snake got one there one night. [ i got the snake ] the chicks have about gotten independent now, stay with momma hen only sometimes. they have moved right in with the flock of 1 RIR rooster, and sex links. the others hens or rooster does not bother them at all, and they fight with the older members for food when i scatter it at night, getting them shut up. they moved into the flock, and set their suitcase down. we always had yard biddies when i was a kid [ rural MS, 50's ] and just don't remember anything bothering them. i guess the population is so great now, america has been paved over, and the wild animals have lots less habitat and more competition for food and quarters now.
