I have 5 girls about a year, I've suspected this in the past but am sure this is what's happening now because I just witnessed it and it was barbaric and disturbing! I know the girls are a little stir crazy and can not wait for the spring when they can free range more. They have a very spacious coop for just 5 girls. They have fresh water, delicious snacks and homemade organic food everyday. I've mixed in crushed oyster shells with their food. The recipe I used is from an experienced chicken owner so it's packed full of what they need. They get all our leftovers and delicious scraps like peeled squash, potatoes, bananas, apples, pears etc. I can't imagine they actually need the eggs is what I'm getting at, I believe it started out of boredom in the winter because they definitely do not like going in the snow. There is a flock block in there too. The comments I've read about filling plastic Easter eggs with spicy mustard didn't have good reviews, so I didn't bother to try that. There are 4 nesting boxes and I've covered the front with fabric curtains because I read somewhere that if it was dark in their boxes and they couldn't see the eggs they wouldn't eat them. I've also put golf balls in each box so they'd peck and move on. But what I witnessed today has me so upset and frustrated ... While I was in there changing the water and bringing fresh food, one of the girls was in the box and I heard pecking so I peeked in and she was pecking the walls while sitting there out of frustration because the other girls were circling around her and kept jumping up and walking in the box while she was trying to lay. I became her bodyguard and was shooing away the girls to give her some space. But as soon as the egg came out it was a free for all. They all jumped into the box in a hurry to devour the egg. I was in shock as it seemed kind of violent. Please help, I'm so sad and confused.
