Hello, we have 2 Rhode Island Reds that we integrated into our flock of 5 about 14 weeks ago, maybe a bit longer. We integrated them slowly but even today, they have yet to be accepted completely. The 2 Reds came from the same batch that was hatched by a friend so I guess they are "sisters". One is doing very well, has now grown to be almost the biggest girl we have. She has finally started roosting with the others even though there is a lot of bumping going on in there at night before they settle. Her sister I have discovered, lays at the bottom of the coop as close to big sis as possible - but thankfully not under her! She is much smaller, her comb and around her eyes are very pale, and she seems to have really poor balance. Neither of the 2 have begun laying yet, though about a month ago, I did get one tiny egg from one of them. The little one is very friendly and does not try to run from me at all. I can easily pick her up and pet her. The bigger sis now tries to get away if I reach for her, but I don't take it personally - ha! The little one, if I set her down, even super gentle, loses balance and stumbles a bit. She is also very easy to literally push over. She does eat and drink very well, she walks all around the run and will eat little snacks when I offer - dried meal worms. I have checked her for mites or bugs - nothing. I don't see anything odd about her vent either. I do know both Reds are still bullied a bit, and are sometimes kept from the food and water at times, her a little more (I think because they see weakness?) I am not sure what if anything I should or could do about this. Any ideas, suggestions, or advise from someone who has experienced this would be greatly appreciated. Thanks!
