I don't know what to do. My brother in laws two dogs chased my chicks while I had come in the house quickly and now two out of 16 won't come back. They scattered everywhere when it happened and it took them hours to come out. Sun is down here in Maine and I am still missing two BR chicks. They are four weeks old. I have left the coop door open a bit because my other chicks who are four weeks old are in their brooder and my seven week old chicks are on their roost. I feel like a failure. I don't know what to do? Do they always come back at night? eta I still can't find the missing two. I wonder if they will make it through the night. Did I mention I feel terrible and sick to my stomach? update- I went out first thing this morning and I can't find them. I still have faith though. As the day progresses I hope they come home.
