Anyone with advice on this, I would really appreciate some guidance! I just got home from work and one of my 3 chicks has this weird swollen lump on her right side chest. It is not her crop, I can actually see through the skin and it is rather clear in this swollen area. I checked on them this morning and didn't notice anything and It wasn't there last night when I was actually holding her so it has developed quickly! Any help would be so appreciated!!
