I will try that tonight if nothing else the salt will burn the heck out of them. sorry to all the mouse lovers, they are not good in a coop.
My bad on Zoe's age she is only 8 months old and looks to be the same size as your boy, what is his name. Zoe did alright in the heat her room has air conditioning in it and I only walked her a little ways down the road and we have a nice shaded lot. On really hot days I moved her to the woods or just took her out to do her business. I wish I had some other animals for her to bond too. I do have a really cool story though about her that brought tears to my eyes and chills down my arms. Here it is
During the end of summer I was cleaning out my breeding pens and had Zoe tied up near me (she is a puppy and runs after everything, she has a long lead) our Amish neighbor has a large flock of sheep that usually roam 40+ acres behind us, they stay to the back where it is cooler and has shade trees, well, I had to dump a barrel of straw in the compost and when I was rounding the corner I was stopped in my tracks, every sheep that was on the back 40 started walking up to the fence line, one by one they came up to Zoe and nudged her and she did they, they took turns sticking their heads through the fence while she gently pulled at the wool on their heads, and smelled them, on lamb in particular kept putting his head on hers and she kept gently nudging his. I was like they all knew they were meant to be together. I was sad and happy in the same moment, sad that she didn't have her own flock and happy that she knew what her job was, I hope to get her some mini goats this spring. I still get tears thinking about that moment.
