My RIR who I believe to be approx 5 years old is showing some signs of aging...I rescued her last fall and she has been doing great..was the queen hen up until 3 weeks ago when we had to start fencing up the crew all together after a fox attack. Her and my other 2 adult hens and one roo were always free range and my RIR Gretta was the lead hen..always laid an egg a day and was the one that put the other ladies in their place. 3 weeks ago we had a fox attack with the fox returning being able to snatch the chickens next door multiple times..In fear that she would return for my Roo that got away..we had to put everyone together. My 6 younger teenager chickens are now with the adult hens...they have been togther when I let them free range supervised but now that they are all together in one HUGE run..Gretta seems older. She is not really the boss anymore and just seems like she is depressed..has not laid in 2 days. I know she is at least 5 years old if not older..I checked her vent last night in case she may be egg bound but did not feel anything, She is eating and drinking great and still comes to me for treats but something just is off with her...she just seems like her personality is shrinking...I feel bad I know she loved free ranging. Could it be the Rooster that bothers her? Gretta was the last of a flock of 12..was left alone to fend fer herself and was kind of left to die when I rescued her...she acted like the rooster up until we got our roo..I am ok with the no egg laying..I just want her to have a healthy happy life...how do you care for a aging chicken? Does the diet change? Should I seperate her in another run with my other 2 adult hens.away from the roo and younger chickens? They were all together free ranging and were the "bad girls club" as the DH like to call them! I would love to free range them again but with the fox knowing they are there..I know I will lose them within a day or so...what to do? Will she adapt to the change? I have only had chickens since last november when Gretta was my first...I hate the thought of her being depressed..am I crazy?
