I let my 11 wk. old chickens (11 gals & 1 Roo) out to free range this afternoon. They were out for about an hour and a half before my daughter pointed out to me that Izzy was missing. Izzy has always seemed to be sort of a loner. She seems to get along with the others, free ranges with them and everything but she seems do it from a distance at times. At first when we didn't see her I figured she was in the alfalfa patch they all were starting to discover for the first time. When she was no where in sight we checked to coop. There she was sitting on the highest roost all by herself. I don't know if she was in there the entire time or if she retreated to the coop when it started to rain. The others took cover under the coop till the 10 minute shower passed. I picked her up and placed her in the run with the door open and she joined the others on their scavenger hunt in the yard. Is this a sign of being ostracized? She doesn't seem or act sick. Replies would greatly be appreciated for I'm still green on a lot of this chicken stuff.
