I have no idea how it compares.. I don't have chickens yet.. they come by the middle of the month .. I have only started to increase my flock more this year.. and that has been through my own breeding which hasn't yielded the best results... truthfully, i have the same amount of birds i had last year.
I was also going to add a pair of birds of a different breed and that fell through too.. so for me, no duck math does not exist..
lol Yes its true, they are one in the same. We started out with 2 Pekins, then DD decided to switch her dairy goat project to ducks for 4-H so we got 2 more so she would have a pair, then DH started liking DDs Mallards so sent me out for 5 more! lol Then I decided I wanted Rouens and got some eggs to hatch, well that didnt work out. I ended up with 1 jumbo pekin/rouen mix being the only one to hatch. Now she is lonely and I want to find another duck around her age lol.
