We started feeding weaned calves, our coming 3 year old cows and open cows last week.
The bales have had about 12" of rain on them in the last few months but there is basically zero damage.
I am MUCH more concerned about the moisture of the hay in the windrow when baling than the moisture that comes down after it's wrapped up.
And of course it depends on your baler. Our NH 7090's make a nice tight bale.
