I say flock but actually I just have 2 one yr old laying chickens. And I want to get 2 more chicks or pullets- from my understanding, if I introduce two new baby chicks or young pullets to my 2 existing older chickens, the older chickens will take care of them and mother them and be nice. Would that be true? According to what I've heard chickens bully newbies. But I just have 2 very friendly and quite lonely chickens (they make a big fuss and sit dejectedly alone when the other chicken goes inside to lay an egg, it's also hilarious when they lose each other in the yard and try to find the other one again) and a very big yard so I think it'll be okay. What do you think?
