I noticed my hens often appear to pant when they are sittin in the nexting box?? Does that mean they are laboring as they expel the egg? Today is not a hot day at all...in the mid 60* s...so heat would not be a factor. None of the others are panting either. So can I assume my girls are ''breathing and pushing" ?? I had one hen sit in the next for atleast an hour before she layed...while some of the others arent in there 15 min and are done. Just wondering about this today as I watch my hens in the box.....? N-e-s-t I really can spell..LOL!
