Ive been wondering... I understand most people wait a bit after pullets first start laying before collecting hatching eggs. But why is this exactly? Are the smaller eggs just less fertile? Are the chickens that hatch from them stunted or otherwise compromised as adults or just start out a bit smaller? With our muscovies I couldnt see anything wrong with the first hatches, and we let them set as soon as they had laid their first clutch... Say you wanted to accelerate a breading program to get to your end goal a lot quicker--what if any would be the downsides of breeding the pullets sooner than later?
