I recently bought a hen (recently being yesterday ) and I got her from a flock of three. There were the two girls and the roo. I'd like to know if she is still laying fertile eggs? I know that a hen will continue laying fertile eggs for two-three weeks after she's been with the roo, but I don't know if my girl has. Is there anyway I could know? Besides asking the man I purchased her from if the roo and her had been together? And if the roo and hen had been together,could I hatch her eggs? Thanks! Oh,and I haven't got any roosters, just my girls.
