Hi all, We have had some rapid changes around the coop... First of all, we lost the little white rock pullet I just bought a week or so ago! She refused to go in with the others at dusk two nights ago, and I couldn't get her in. She was still eating, so I figured she would go in shortly, and left a little hatch door open for her. We have not had a single predator attack (except a hawk) in the entire 3 years we have had the chickens, so I felt pretty safe leaving her in the pen. It's very close to the house and the dog run is right next to it, and I think that's probably why we have been so lucky. Unfortunately, this little exuberant pullet was too visible in the dark, I guess, and was most likely taken by a possum. They are nasty - they just seem to kill for the heck of it, he didn't even eat her! We discovered her when we brought home the 'chain gang' - my name for the 8 sad looking '09 Rhode Island Reds I got from a guy a couple of towns over. They have been in a too crowded environment and have had their tails completely plucked clean! I've never seen a more sorry looking bunch, but they seem very excited about eating actual green grass and having room to roam. If I had gone myself to pick them up, I might have been a little skeptical to get them, but hubby brought them home and I didn't get to see them until it was dark and he had already put them in with the others in the hen house. Now my question: Would you do anything preventative when you introduce a new group of adult hens to the ones you already have, for instance deworming them? Or would you wait and see if any of them have any symptoms? I spent about 45 minutes there this morning with them to see if any behaved strange, but they all seemed in good shape - eating vigorously, clipping grass, went inside single-file to drink, and seemed to be respectful of the old crew. The rooster enjoyed the new selection of broads... I noticed that one of the hens had a comb that was hanging over instead of standing up, it looked like she was going to church with a new hat! Otherwise I was a little surprised to see that their combs were bigger and redder than my rooster's.... but I guess that's a breed issue. I had one RIR once, but it's a while ago - she passed from old age and was old already when I got her. Any input?
