I finally got 3 chickens (Faverolles) about 2 weeks ago. As I bought them they where 6 to 8 weeks old I was told. Since they are the first chickens I have ever had the breeder told me that I can put them outside as soon as it gets a little warmer. Yesterday we finished the coop and since it is already 77F outside we already transfered them into their new home. 2 of the 3 have grown since we got them and the smallest one was just as big as one of the bigger ones. So after their first night out in the coop I came outside this morning to open it up only to find one of the bigger ones dead next to the food. The other two seem to be fine. What has happened? I have no clue only the fact that it didn't grow at all since we had it unlike the other two. And I think the poo was very watery and even with some blood in it. Maybe someone here can tell me if we should we put a red light into the coop for them at night? The coop is insulated and I thought it would be warm enough for them.
