My CC have started to show up on top for feeding again, and it's only February 21st! NW Arkansas.

Pardon my ignorance, but when do they normally show up?

Here, about March 20, normally.

Nice, I put in about a dozen CC in my pond. I keep waiting to see them feed with the BG, but so far nothing.

My CC have been feeding really well for a few days in a row now. How long to get them fattened back up after a winter of no feeding and an on and off again March? I need to take some out to eat, and avoid a summer kill, but don't want to dress skinny ones. Would ten more days of good feeding be enough?

Here's a recent video of feeding activity.
