Is there a time frame where we should know if a hen has internal injuries? My dog injured a hen today and tore out a lot of feathers. I can't find any bite marks but tonight while making sure she'd gotten herself on the roost I saw a small amount of dark red stuff on her vent. I can't tell if it's came out of her or if it's a stratch. It hasn't gotten worse nor has it gotten better. I went ahead and took her out of the coop, gave her a bath and scrambled eggs. she's been eating feed just fine, acting completely normal. I have her caged inside since she's wet. Just wondering how long I need to worry. It happened 6-7 hours ago. Wanted to add that she's pooped a few times and there is no blood in her poo.
