Ok, I'll admit it, i'm stupid when it comes to pigeons. Where exactly is the crop and how big does it get when full. Can someone please send me a picture of a full or empty crop of a 10 days old PLEASE. I don't know if i'm over or under feeding my little one. Help ASAP!! Is the gullet or crop just at the neck area or is it the whole front and lower abdoman?? Picture please!
