I'm sorry but I have no experince for lizzards, but for pigeons in the winter they need about 14 hours of 'sunlight' for them to lay. That is all I can say sorry. There is a type of bulb but I can't remember the nameIs there a certain light bulb that can be used for sunlight? I think they use them to grow weed. We have to have a special bulb for our iguana and if you don't use it it will not grow.
THANK YOU GLAD OTHER PEOPLE SEE THIS .. THIS IS TOTALY WRONG TO TREAT A LIVING THING LIKE THAT!! THATS ALL I HAVE TO SAY... I'M DONE WITH THIS TOPICIf they are kept in those cages all the time, then it is awful. No one can say that they are happy like that. I don't care if they don't know anything else. That is not even having a life. That is being treated like a thing, not a living creature. All living animals and birds need to be able to move around and do things other than stand there in a cage and be used for breeding. Pigeons have minds and are smart, and they have nothing for enrichment. Just stand there and breed. Anyone who can try and justify that, is viewing them as not having a brain or needs. That's sad.
