Hi, I'm hoping someone here can help me understand what is going on with my new baby chicks. They are only 2 weeks old and out of the 8 I started with I'm down to 5. There were no visible signs that would leave me to believe they weren't doing well until they really weren't doing well. One minute they were all chirpy chirpy eating and pooping like mad with all the other chicks and the next minute they won't leave the heat lamp and can barely hold their head up. The only thing I have found that they all had in common was this 'pasting up' thing. I've read alot about it being a very very serious issue so when I discovered it I reacted immediately but to be honest I don't know how long they had been like that. It definitely wasn't days but maybe a few hours. So I'm wondering what actually happens to them during this state to make them go from bad to worse in a matter of minutes. Or maybe that isn't it at all and it was something else entirely I'm just trying to understand so it stops from happening to the others. If it is the 'pasting up' what can I do to help avoid it? Does mineral oil really work or will that create a new problem of the other chicks now having something to peck at. The temp is fine, they are on medicated starter with fresh water. They have enough space. Their cage is fairly clean. What else will help narrow down the reasons..... Any advice/suggestions are greatly appreciated!
