HELP, my horse ate a birdseed

My grandma used to let her horses loose in her yard from time to time (the entire place was fenced off) but she was one of those "bird feeding people" too

They constantly attacked the bird feeder and ate all the seed off the ground. I can only speculate, but I assume its because it is seeds and grains, which of course horses love. They never had any issues, minus my grandma pestering them for chasing away all the birds

It may have been a deer block rather than a birdseed block -- I would suggest asking the neighbor what it was, specifically, as some blocks may contain ingredients you would not want to feed a horse.

We make a pen right next to our bird feeder and Casey figured out how yummy it was and started eating it. She was fine.

Hope all is ok. I used to give a bran mash if my horse had a stressful day. Usually the horse is fine and I am the one in need of a nice glass of wine or hot bath or both.

Wow! I didn't think of that! Thanks! That is most likely what it was! Haha, I was so upset all I could think was, "why would someone put this gianormous bird block out here on the ground?" I just didn't think of deer.
I have watched her all day and she is doing fine....thank heavens!!! I went into a dither - in overdrive!!!!! But, I got the realtor's name and was going to hunt them down to see if I could ask the owner if I had to!!!!
She loves to play, so we played many times today. It gave me something to do while I monitored her. I am played out!

haha...thats about it in a nutshell!
