I am new to the world of raising my own backyard chickens, and will probably have about 100 questions. I have 2 Buff Orpingtons and 1 SLW pullets that I bought at my local farmer's co-op. I'm pretty sure they're about 3 weeks old. The problem is that the 2 Orpingtons seem to be very friendly with one another- always cuddled together, eating at the same time, etc; however, the SLW seems to be the "outcast." Every time I go to check on them/play with them the two Orpingtons are together and the SLW is perching on the side of the box or in an opposite corner by herself. I'm wondering if this is normal and if there's anything I can do to help her not be all alone? Thanks!
