A few months ago I bought some ducks off of craigslist. One of them started laying for a few weeks then hasn't laid since. Then another one was laying pretty consistently for awhile then after some of the ducks died she hasn't played since. I know age can play a factor in laying as long as stress but my other duck has been laying everyday even after the attack. SO is there anyway I can tell a ducks age? Is there anything else that you could think of that could stop laying like this? Any help is appreciated.
