I haven't been out to the place in a while (about 3 weeks) and I noticed today that a cow has cancer eye (correct?) now I'm not 100% sure if she is going to have a calf but she should be due in late June I belive...we've never had a cancer eye cow before and I have no idea how fast this will progress...I know every case is pretty much different but for those of you that have seen this before how fast does it grow...what my main thing is should we let her raise another calf??? or send her on her way now...
