I have a little (I believe) Millie mutt mix hen that lays small cream colored eggs. This past week her eggs have that lumpy eggshell look. Like calcium deposits all over the eggshell. When I bring them in to have a closer look the stuff scrapes off. I've seen this before but it was minimal. Hers are getting ALOT of it on her eggs. Am I giving her too much in the calcium department, or is it her manufacturing too much and it comes out in her eggshell? This is what all of them eat: regular layer mash, oyster shell in a seperate dish for when they want it, plenty of water, and I give out treats daily. Treats include: leftover baked potato, pasta, a little bit of cheese here and there, veggie scraps. They all eat the same thing, but her eggs are progressively getting lumpier. Am I doing too much in the treat area? Or is she just going thru a phase? Should I worry? Thanks for any input.
