Shifting play structures

I moved the haybale play structure from its former location in the south corner of the greenhouse......to the opposite side of the greenhouse.I have about 9 bales left, that are very dry and falling apart, that I am cycling through the coops as bedding and then to the garden for mulch.  While stored in the greenhouse, the bales  are providing caves, entertainment, and vantage points for the bored birds.  And carbon for the ground.I dropped one unstrung bale into the middle of the room.  There's little they like more than to take apart a bale of hay.  The normally uptight guineas, in a rare moment of repose, used it to cash out in the sunshine, and fell mercifully silent for a good hour.The haybale move -my every move closely monitored by short attendants - served two purposes.  The sitting haybales had kept a big patch of dirt wet and scratchable, so each bale I moved, the hens rushed in behind me to dig. It's fun to work among the hens, them all up in my business, making interested noises, having their own dramas.The new play structure was a novelty, therefore highly entertaining to explore.You know when something is overwhelmingly interesting when ALL the birds fall silent.  They're that busy.  Too absorbed to talk about it, to make announcements. Then little burbles of speculation.All three of the resident breeds explored the new apparatus, hopping up and over it and sidestepping along the high poles, but - I didn't anticipate this- the Silkies wholly claimed it as their own.Three dead mice were unearthed, precipitating the inevitable lively mouse run.After a thorough inspection and finding it pleasing, the Silkie tribe moved in en masse... and settled in for some hard lounging.I'm going to move the bales at least once more, and I expect similar excitement and results.  In return they will thoroughly distribute a mulch layer in the greenhouse for me.
