Hi, I have a brahma hen and we have had her for about 12 months now, we were told she was only a year old when we got her but i believe shes around 3/4 years and hasn't layed since last year. She is very large for her breed, but I noticed a few weeks ago that her crop is huge! Now she is a greedy bird, but should they be the size of a tennis ball? She is otherwise eating/drinking and pooing normally. Am i just worrying over nothing?
