retention

anyone else have trouble with does losing/pulling out cidrs? 5 days prior to scheduled cidr removal i notice one laying on the ground next to a feeder. when i ran my 7 does thru the chute 4 of them had lost their cidr. i replaced three as thats all i had on hand. when we ai'ed , we thought one...

I am wondering if there is a connection to late antler loss and late breeding. If loss of testosterone makes antler fall off? If the last doe is caught late, does he lose his antlers later because his hormones are still elevated? :confused:
