Step siblings? My sister, her brother, their parents? But that sounds exactly like something my father would have done!
Hi!! No worries!! It is so easy to miss posts!!!
From what I read, I didn't think this was lice - When I lived in Samoa, I saw a LOT of head lice, and lice on animals. Nasty creatures!! I do think it is mites though, since the other 2 that are like this are different breeds. I am not sure what this one is, but one is a Salmon Favorelle, the other an EE. I had tossed the EE into the bottom pen, it's missing feathers weren't as severe as this one. I'm pulling all the chicks out today, and will see how extensive this is. I'll clean and treat them all.
They do get a starter feed. By this point they are getting the regular stuff. Only the first couple of weeks do they get the medicated feed. They get electrolytes/vitamins in their water once a week. I'm giving it to them every day that it's super hot. Since these guys don't go outside, they are not getting any other treats. I need to pick up some grit and start adding to their diet.
Again, thank you all for the advice!! I'm going to go back and find the name of the medication I should use. I'm also going to adopt the natural treatment for all the other coops - and spray the walls with the garlic mixture. Should be an interesting aroma out there.
Happy Hatching everyone!!!
