I have a older hen that is almost through her molt.I noticed a few weeks ago she was having a hard tine pooping.when she did it was little and hard.I mixed in some molasses in their water as I had read that would help.I see very little poo if any where she roost at night. I did my molasses and water mix again this morning. I thought maybe the grower feed I switch them to when they started their molt. May be the cause. I took them off of that and started them on flock raiser. I still see no difference. Any suggestions would be greatly appreciated.
