We only have one in the house- she came in because she was sort of staggering and looking poorly and the other girls were starting to peck her. We brought her in to recover, she staggered around for a couple of weeks and, in the process lost any winter acclimatization she had. I just can't put her back outside in the single digit temps we have here (and I'm not keen on sitting outside to see if the other girls will accept her back). She is inside until spring and we can re-introduce her to the sisters. (and, in the meantime, she has recovered and has started laying again- an egg every other day- to pay us back).
