I am having some new grill work made for the front of my foaling stall. How close do you all have the bars placed with foals? Standard grills 3.25" spacing, but would you have it made even closer knowing foals will be in there? Since I am having these made I can do what ever I want...I was thinking 3"??
Because of the fact that foals are in the stalls, I won't have bars that go all the way down to the floor. I only put bars on the top 3 feet. If you want more air flow, find a stall manufacturer that uses a steel 2 inch x 2 inch squares. No feet or legs or noses get stuck with those.
Our broodmare stall screens have wood at the bottom...for 2 feet and the rest of the screen is expanded metal...very small (1" diamond shaped holes). You can always fasten a piece of plywood over the bottom of the grill for foal safety. I have seen horses get their feet/legs in some pretty impossible places. I try to reduce the risk every way possible!!
Definitely -- if you're custom making your stalls, don't use anything on the top that a foal car rear and get a leg into. There's too many horror stories of foals getting legs through the bars and breaking them. I would think a grill with squares or diamonds no bigger than 2" are best.
