I recently purchased 2 guineas, 2 turkeys, 1 new Hampshire red, 1 is brown, 2 dominique, 2 English blue orpington, and a mystery yellow chick. All were purchased at rural king besides the orpingtons those were at a local farm. The turkeys I had got to eventually eat. The rest are all for pets. As they all started getting feathers and growing I noticed the little yellow one growing really quickly weighing double what the others weigh and still barely growing any feathers. I realised I have a cornish cross, as I've had 2 in the past. At first I was devastated, already being attached to her/him. I know their life expectancy is short due to health issues of growing too quickly. I'm determined to help her/him stay healthy. I plan on monitoring feedings, and once shes done eating take her out and watch her run around the yard on her own for excersise. Please any advice about this breed or your own experiences is much appreciated.
