So my hens/pullets (not sure which to call them) are 5 months and 1 week old today and ever since my barred rock starting laying eggs (the only one laying eggs currently and a little before she started) she's become very food aggressive towards some of the chickens (the smallest Easter Egger fluffy, the smallest RIR Baby, and occasionally the bigger RIR Pecker) she use to never pick on anyone and now she grabs them and doesn't let go (usually she grabs the wings but I've caught her holding fluffy's neck a few times which really concerned me) the first time it happened I thought she was protecting the other EE Gray because baby (RIR) has been chasing gray away from the food and pecking her and one time I moved baby away from gray with my foot pepper grabbed baby's wing and held on until I tapped her back to let go. Ever since then she's been agressive and we noticed if she isn't there they all are calmer though big bird (the biggest bird we have that we don't know the breed of since she's probably a mixture of a couple breeds) tends to pick off the feathers of the lower back of some of them with or without pepper there (noticeably Pepper and Pecker) but she doesn't do anything else besides that not only that but Pepper has layed a couple spotted eggs and a soft shell egg, I'm wondering if she's stressed out or maybe I'm doing something wrong with her nutrition? It's been in 90's/100's here almost all summer so I thought heat might of been an issue but we've had them inside during the heat of the day yesterday and today and it still happens. Overall I'm wondering if there's a way I can have Pepper stop bothering everyone because is she calms down I think everyone else will too. Any ideas/advice?
