So here's the deal, my 30 week old Delaware pullet was the first one my chickens to lay. Her first egg was sometime in mid-late February. She was laying pretty consistently until last week, maybe Monday or Tuesday I noticed it and it became more regular. I had gotten a couple shell-less eggs before but figured she was just working out the kinks. Lately some eggs have just the membrane or she just squirts out the yolk and white. I have found membranes in the coop and yolk/white spots in the shavings. I know it is her because as I was closing the coop for the night I heard something like water hitting the floor. At first I thought it was a really watery poop but discovered it to be an egg. I have tried giving her oyster shell but she doesn't really eat it. I have heard not to feed it too much because it can damage kidneys, not sure if that is true. My main question is what can I do to get her to lay? She was in some discomfort last week I think but not since then. Any help is greatly appreciated!
P.S. I only posted now because I thought she would work it out on her own but not yet.
