Hello! I've got 3 Wyandotte chickens - 2 hens and 1 rooster. They all seem to get along, although the rooster seems to prefer and hang out with one hen in particular. Both hens have been laying nice eggs. Recently, however, I have noticed that I am seeing some eggs that have too much calcium and today, one was a very weird soft egg. I don't know which hen is laying the "off" egg, since they all share the same coop. During the day, they run free on the property. I read the article on egg abnormalities: https://www.backyardchickens.com/articles/common-egg-quality-problems.65923/ which was very interesting. A soft egg is not enough calcium, a calcium covered egg may be too much calcium, according to the article. The reason can also be stress, molting, or infection bronchitis. Both hens appear very healthy, running around being hens. Both hens are on the same diet and one of them is laying perfect, smooth eggs. I give them a mixture of egg-laying mash from the co-op, mixed with one third cracked corn, so the rooster eats the same thing. I did start giving them chopped egg shell to add calcium to their diet and I was wondering if that was too much. I also noticed that either one or both hens sometimes lay outside the nesting box - around a nearby tree which has leaves around it and little nooks and crannies. One (or both) sometimes lay their eggs there. I am wondering if the stressed hen is going there to lay in peace. Would a hen who appears to be a loner and at the bottom of the pecking order be stressed? Any thoughts on this would be greatly appreciated! Thank you so much!
