relating back to my first post. i am a new chicken owner. i had first wanted to check that all our chickens were hens and got confirmation from a few replies that in fact they are all hens. yay. they are all just about 4 1/2 months old and we have one laying eggs. today was her 8th egg but had skipped one day with no egg. first egg was medium, then next eggs were good size but have gotten smaller. is this normal along with do the yolks look like normal unfertilized eggs. attached is a photo of the first 6 eggs, in order from oldest to most recent. and the yolks are from the 7th and 8th eggs cracked open this morning which were the size of the 6th egg but normal brown color
