My hen laid a "rubber" egg. I am pretty sure this means she needs calcium. I have 2 older hens & 2 chicks just over 2 months. I had 8 other chicks but they were all roosters & I just recently traded them for the hens. I am confused about what feed to give them.The hens need laying feed & the chicks on the chick feed. Do I offer both or will almost 3 month old chicks be okay with adult feed?? Here are some pix of the "rubber" egg. Sorry they would not load in order.
