I have a pair of female mallards who are 8 mos old.  I used to have three females & one drake who I hatched all together last summer. At 5 mos. of age, all three females were laying while the drake was around. I gave away the drake & one female @ 6 mos. of age and about a week later the egg laying stopped.  Do females need the presence of a drake to produce eggs?
