Hey there. I've got two pigeon chicks, about a week and a half old. One is big and well-feathered, and the other one is tiny. A bit bigger than how she hatched, with a little bit of feather development. Pretty active, eyes open. Mom's feeding both, but the smaller one's crop is pretty consistently full of water more than food compared to her brother's, which is always full of feed and milk. Is there any way to fix this? the parents aren't sitting on them which doesn't help either since she's not feathered yet. I've been trying to separate the bigger baby whenever the parents are feeding, but I can't seem to catch them in the act to do so. Any thoughts?
