I think all my girls are bred from the Rhode Island Red (I'm not up on all the breeding info).
If any of you have seen my post in the chicken health thread, https://www.backyardchickens.com/forum/viewtopic.php?id=531823
You will be glad to know that Tikka has been showing signs of improvement today. Been eating and scratching around, with her tail up, even when stood upright
Checked her vent and crop, all seems OK there.
She is not fully back to herself yet, but seems happier.
Have started all the girls on a 7 day course of Flubenvet just to be sure.
