Hi, I have a problem with my girls some are a little older(nearly 2.5 yrs) which were ex battery hens. I recently purchased 15 pullets , altogether we had just over 30 girls and a roo. The eggs came quicky about 22-24 per day slowly but surely the egss slowed, firstly because of the weather it got a little cool and stayed that way for a while. Then we had lice (all fixed now) which caused loss of feathers. I lost a few to age so now I'm down to 25 but I'm only getting 10-12 eggs daily. So I guess my question is should I get rid of the older girls (I'm not sure if they're still laying) I have tried giving them protein and some oats or barley. Don't know what else to do to increase eggs Pleas help!!!!!!!!!!!!!!
