My chicks are now almost a month old. (Wow, time flies!) As they've grown and sprouted their feathers, they've all (9) developed what looks like either a large lump on the right side of their chest, or just an uneven chest (with the right side protruding much further). My digital camera is broken, so I can't take a pic, but does anyone know anything about this? I was very concerned when I noticed the first one, but they all seem to have it. And they're acting just fine. Lots of energy, normal eating, normal breathing and pooping. Any thoughts? Thanks.
