I so appreciate your input, Teach1rusl. I do need to take her out and see how she does with the others. She and the rooster that came with her, are much bigger than the others we have, but I did see the little ones chasing the rooster. A very funny sight, actually! On the other hand, I caught him jumping all over a very small banty rooster. We are having very unusual cold temps here in central Texas (near Austin). We are making coops from two 5X8X7 storage boxes...called Pods, I think. We just don't have them ready to be occupied yet. We have only gotten a pop hole put in one, but DH hooked up a couple of drop lights to go in there, we spread hay, and are keeping all of them (21) in there at night. Too many for one coop, of course, but being desperate, we had to do it. It is working great so far, and I sure sleep better knowing they are at least in there instead of in their partially enclosed cages they have been in, which didn't provide shelter except from the wind and rain. It was still COLD. It was actually 10 degrees here the first night we put them in the box, and we couldn't catch two of them. The next day, one of the two (a perfect, beautiful, white banty with nice long tail feathers and a big red comb) had frostbite on the comb. I caught him and coated it up with A&D, and wonder of wonders, I believe it saved the comb.
Anyway, crowded or not. they are going into the box at night until it warms up a bit. I'm watching temps today...it is 45 now, and this afternoon if it gets to 50, I may put the chicken out for a bit and see what happens. I also have a little sweet banty in the house in a pet taxi (all our cages are too big for the house except one, and the other chicken is in that one). The big rooster was really picking on him, and he was seeming to be sick. He isn't though...I just think he was reacting to the big rooster.
Thanks again. It is wonderful to have people to "talk to" who understand and can fill in the blanks for others who have questions.
