One of my babies is missing of course it has to be the biggest and healthiest of the bunch. there are no virtually no predator attack possible since nothing enters my yard since my dogs typically roam it they were inside today so the chicks could play. the chick would be about 4 or more weeks old. how far would he wander from the rest? i don't hear a lost call so i have a bad feeling hes gone. no feathers or fluff i should say. no body. is 3 weeks old enough to come back if it escaped the yard?
