i'm very new at this. i got 5 baby chicks for easter, the are outside now in a big dog kennel. i was wondering if i let them out will they stay in the yard? i don't want to lose them because i love them very much, i see people who have chickens and they just run around unfenced. do i have to train them to stay or will they just stay on their own? they've been living outside for a week or 2 now. please help me
