Hi, my 3 mixed chicks are 10 weeks old now (a couple are maybe slightly older). I just bought them a few days ago and they currently live in a large dog cage in the house. I have 4 adult hens outside who are an established flock but yesterday I tried them outside with them in the run and they got on fine apart from the usual pecking each other over food (nothing major). When can they go out permanently? It's Scotland so it rains most of the time and there's a high of 19° at best!!
