a couple of days ago, I noticed one of my barred rock hens limping a little bit. They were born in April, and have been laying for a couple of months now. Yesterday, she wasn't limping as much, but her tail end was downward, along with another one of my hens (i have seven). Last night i researched this site about egg bound hens and it all matched up to what they were doing, so last night i was up for quite awhile, soaking them in warm water and massaging them. This morning, there wasn't a sign of an egg. I soaked them again, and now, (nighttime) the two of them are in the nest, (still no sign of egg) Any suggestions ?
