There was another rubbery egg (on the ramp coming out of the coop this time) this morning ... my pullets are 21 weeks & 19 weeks ... my 21 week old laid her first egg on 7/3/13 & my 19 week old laid her first egg on 7/5/13 ... up until yesterday all the eggs have been normal ... THey have access to food (Layer pellets), water, grit & oyster shells 24 hrs a day ... Could this have been caused my the heat/humidity we have been having? (I have been putting frozen jugs of water in there run to help keep them cool & I have wet down the dirt in the run as well) ... Is this normal because they are new to laying? Am I over-reacting? How long does this go on? I am doing everything right, correctc? At what point should I start to worry? I probably sound crazy ... LOL ... but my hubby & I have become pretty attached to these 2 ... I appreciate all the help/info !
