Hi there! I have some 5 1/2 month old chickens.We live on 15 arces. We have 22 other chickens. Coop is a good size. We use poultry netting to give them a nice size run. Last night when checking in on them I notice a girl that had a really pale comb and was a little slow moving. She didn’t make it through the night. I really new to this. I tried to looked for mites or signs that she was egg bound being the issue. She wasn’t missing any feathers nor did the vents look dirty. I felt her abdomen for an egg but couldn’t feel anything out of the norm. Maybe I wasn’t feeling in the right place. I don’t want to lose another chicken. Any other suggestions on what could have happen to our young girl? Or what else to be on the look out for?
