My mother-in-law had some renters that gave her a dozen fresh eggs every week and many times when she'd go to crack them open, half the white would stick to the shell. Now the renters are moving out and can't take the chickens with them so my mother-in-law has moved their coop to her place and is wondering if there is something wrong with their diet causing the whites to stick the way they do. They were free range when the renters were caring for them and my mother-in-law intends to do the same once they are settled. Could it be that they weren't getting enough water? I've had chickens about a year and a half and never had this issue. I figured those of you with more experience may know what is going on. I don't think my mother-in-law knows very much about them as far as age, breed, etc.. She didn't tell me how many there were but I could ask. My first thought was that the eggs were old and had dehydrated in the shell but she's certain that they were fresh. She had chickens once a long time ago but didn't remember this ever happening.
