So my mottled houdan bantam rooster (the only one I have) started to develop a crossed-beak last week. It's slowly gotten worse. He did not hatch with it and he's about 3-4 months old (hatched this spring). I e-mailed the guy I got the eggs from (paid almost $80 for 6+) and so far, have not received any repsonse. My white houdans from the same dude are doing fine...so far. So since this happened later in life, is this genetic? Is it curable? Preventable? Caused by diet? I have them on Purina Sun-Fresh Chick Starter (it is medicated). They also have free-choice grit. They also get lots of greens & grasshoppers to eat every day...this houdan is in with all of my others hatched earlier this year as well as the ones hatched last month (one LB & one BA). In addition, about once a week, I boil up all of the eggs that didn't sell & mash them up (shells & all and feed them back to the chickens). None of my other birds in that pen or any other pen are having this issue. The last crossed beak chick I had (LB) hatched that way (last summer from shipped eggs) & despite my best efforts, died about 2 weeks later. Oh and I did use my Dremel tool to try to shave off a little bit of the twisted part last night. He seems to be eating/drinking okay, still but I am still worried.
