Maybe they have found a gusher in the chicken coop!!! I would check their roof out. Is there a leak?
Do you have any kids? One might have been giving them a lotion massage. Your husband might be playing games too. ^^
Lol...I have to admit those are not things I considered. I spent a lot of time in the coop/run this weekend redoing the fencing on the roof of the run ( found a rattlesnake looking for a chicken dinner outside the run the other day and realized he could get in through the top) but I didn't noticed any drips or anything. I'll check again though. Thanks for the reply.
