my ex barn hens are coming up to 3 and a half years old, some of them lay........ most of them don't, when my dad winged (he only had 2 eggs for his lunch instead of his usual 3) he said "you'll have to go back and get some more" i jumped at this unusual offer of allowing me to get more hens and said " ooh yes, that's a good idea" to which he replied "only kidding, don't you dare"
just got to explain to him how my finger accidently slipped on "bid now" hatching eggs from e-bay................
well, he said i couldn't get more hens, he never said anything about eggs
he did ban me from incubating, but that was last year and i think it's run out now
