eggs

Give you hens some crushed oyster shells.
It will help them with egg shell development.

 

Give it to them seperately though - too much calcium isn't the best for those chickens that don't need it. You can provide it occassionally in a bowl, or get one of those pet feed dispensers.

For such a small flock you can use egg shells as a free calcium suppliment too. Keep a largish jar on your stove and put your egg shells in it. the heat from the stove will help them dry faster. When your eggs start getting thinner shelled, take out a handful of shells, and grind them up in a jury-rigged morter&pestle (I use an old slasa jar and a narrow drinking glass).
