Sweet pic, they are enjoying themselves and getting to be chickens.
They require a different kind of thinking and effort to keep clean and active, I hope you enjoy them!
They are not disgusting unless a person forgets they eat more than twice as much as the layer birds, so poop thrice as much, and also grow twice as fast as the layers so they make larger poops more often and are less agile and energetic........from my little squad of 10 non-cornish x meaties I learned, they need four times the space and double the caretaker energy (and ingenuity) I anticipated - mostly because they grow so very fast, eat more and do not roam as much the layers but do like to see bugs, preferably easy to catch bugs.
I am appalled at how some of my friends raise their cornish x birds annually - I am very tempted to ask why they do not just make them into battery hens in little boxes or simply go and collect a bunch of birds from an intensive commercial growing factory then butcher and eat them... why pretend to raise something differently to BigAg when you're not?
These 'family-raised' birds get 1/5 the space of their layer birds, zero stimulation, fed a diet to induce meat growth but poor bone and organ development, etc and then the birds are called disgusting and the owners won't look at them for the last 2 weeks of their miserable lives.
Enjoy your little fluffy Thunder Thighs, (yep, even after many poopy days *sigh*) ....update with pics and share anything you learn along the way!
