Welcome!!!! I explain this to all newbies so they don't get confused lol but I'm actually in Wisconsin but I'm pretty close to Illinois and more importantly I've found some good friends on this thread. I love these people!
Of course I know your birds are big but these are the first cockerals I've grown out from you(the two cockerals we got in 2015 we lost to cocci remember so this is crazy!) I wonder if they will get as big as Moose?! I hope they're as sweet as Mr Dummy and Brick. Gosh I love that roo. You ever move him out you let me know.

he always makes me think of a cloud that and we'll some Greek god strumming a lyre and lueing maidens to the clouds lol. He's such a hunk. How big is he next to you? He seems smaller than my three chocolate cuckoo boys.
No EEs? You need some blue and green eggs
Oooh! How do you like the buckeyes? Are they heritage? Do you have a roo? How are their temperaments? Sorry for the million questions DH2B chose them this year to get so we are ordering some this spring. They're supposed to be good mousers from what we've read. Then again so were the guineas what a flop lol.
Our cats were totally freaked when the rat was in the house. Lol they're good mousers but only indoor cats and they were like "OMG Mom! That's the biggest mouse ever it must be nuclear!" Lol
If/when you're able you should post a pic of the mixed breeds and unknown birds on here. There's a whole area for it but you might find some help here too or post the link to the thread after you make a post.
Just want to say thanks guys I'm glad we're not the only one's that have had this problem. Unfortunately we live very ryrally and they've been cleaning more fence lines in the last year by our house. They've also been cleaning up some shed on our property which of course you guessed it probably made the things show up.
While mice are annoying and I draw the line at the kitchen counter they usually don't make it too long in our house courtesy of the cats but now the rats ove got all sorts of things against. I hate rats now ever since they killed a chick and nearly killed the little lavender boy. I have no doubt if we hadn't brought him in treated him and them moved him that night I believe it would have killed him. He was not a small chick when it happened either he was about 10 weeks old maybe older idk have to check. He also wasn't the smallest chick in the run that night. I have no doubt that the rat attacked the chick and tried to disable it so that it could eat it alive.
It was just terrible. I wouldn't wish being eaten alive on anything it's just sick and terrible. I like wildlife I really really do just not when it interferes with my animals. I am thinking we well have to go with poison next although I hate it. I am not sure we have much choice. It's possible we can stick something over the holes to make it so they can't come out.
I would never have thought before seeing it with my own eyes that a rat would eat through a foundation, or eat a corner out of a building, or burrow under a building to come up in the walls, or disable, kill and try to drag off a chick. I knew rats were bad but even though I've lived in a pretty rural area my whole life or most of it this is my first real encounter with a rat and I must say I could've done without. I feel as though I need to completely wral my house coops and car in 1/4 in thick hardware cloth. Lol
Good luck to us all in ridding our coops of these dangerous pests. Anyone have a large snake? Perhaps that's the best way to rid us of the rodents... So long as they don't get in the coop. We'll just send the snake down the hole lol
