I only have 3 hens who have been together since the start. All three very sweet, but the larger two always hung out together and nested together leaving "Nugget" the odd girl out. Because of this we have always given her more attention and therefore she is the most accepting of my children's "affection." Today I noticed after being in their coop for two days, Nugget was being mean. She kept bumping chests with the others and pecking their combs. Any thoughts about this? Is it just cabin fever or a diet issue? Nugget has also been inconsistent in laying compared to her sisters all along. Funny thing is that her eggs are cream colored compared to the others that are brown and they are all the same breed. Thanks! I look forward to hearing from you all.
