Thanks for the insights.
There's just the two chickens and we get one or two eggs a day so she's still laying. And I can discern no change in her behavior - she's a pretty cheerful chicken. She gets along well with the other, they're usually together whether it's napping or messing about in...
Hi,
I have two barred rocks with plenty of room to stretch their legs and wings.
I just noticed one of them has a red featherless patch between her legs while the other chicken is well feathered in that location. They sleep on fresh hay and they have a big yard.
ETA I removed the snow...
