I keep looking at the bridge and I can't see how a chin's foot could get caught. It could slip through, but they would just push up with their other feet. Their body is too fat to fall through and hang upside down, plus the bead would stop them from doing that anyways. If a leg slipped through and they fell they would just topple off. The slat opening is too long to keep the foot caught, it would slip out. I haven't heard of any other chins getting hurt on this bridge and certainly no proof.
I get absolutely NOTHING if these bridges sell or they don't. I let people who make chin items list them for FREE on my website for my customers and I try any item listed on my site before I list them. The pinched toes are from bridges WITHOUT the bead spacers, how could the toe get pinched in the bridges with the spacers? I would never use wire flooring on a cage bottom or shelf, I used a pan with shavings.
Squeal & protest all you like but don't call into question the experiences being shared by people who have had problems - unless you wish to call them liars? That's not a route you want to be taking.
As Stackie said above, bridges without slack
do not cause problems. If they are designed & constructed correctly then there is no slack between the slats & there is no gap for toes to get trapped in.
Bridges with spacers (of whatever type) do allow toes to get caught. On top of that, if a chin nibbles the spacer bead/wood then there is greater potential for the slats to move & trap toes or, if wide enough, a leg.
Your experience of the chin chewing the wooden spacer & leaving a gap is not the same as a bridge with tightly fitted slats.
Also, when a chin gets it's foot/leg caught in something they rarely (if ever) lift their foot straight up & out of the gap - they do try but usually their foot is twisted already. They don't have the ability to reason & work out they need to straighten the limb & then lift it out of the gap safely. It is this natural twisting/turning motion (at speed & often in a panic) which causes the injuries. Your theory is fatally flawed I am afraid.
There are people on this forum sharing GENUINE experiences of their chins having problems with bridges
of this type.
IF there is a gap between slats, whether it is there due to spacer beads or not, then there is a risk (& yes, a proven risk) of chins getting their toes or legs caught & injured.
These bridges are, in my experience, an accident waiting to happen - I wouldn't ever use them or recommend them & certainly not for small or young chins with little limbs/toes.
