I have around 100 chickens currently, so I'm no help with self control.I'm assuming they are a full crop, unless they start to look different. It's hard to tell when they are going through this baby molt.
I'm hoping that if I don't get into a heritage breed, that I can manage myself. We had a flock of 26 plus some assorted roosters at one point. It was nice that they were all auto sexing, but honestly it was a bit much.
