For whatever reason, my Blue Copper Marans have never been good layers, but recently just plan awful. I have five hens that range from 1.5 years old to 2.5yrs old. I'm consistently getting one egg every other day. They have a beautiful and kind Maran roo and some these eggs are fertile because I've hatched quite a few chicks. They are eating a 22% laying feed and have access to oyster shell. I treated for worms about 2 months ago just to say it's it helped, and 8 days ago did a completely full 5 gallon permethrin dip just in case it was lice or mites. I didn't see any infestations of worms or pests on anyone. I'm about ready to give up and sell the whole flock.
