Female cockatiel
I am having two cockatiels but I dont know whether they are female or male. One day I saw their mating. So i bought breeding box and i fixed that. On 23rd february i found one egg inside box. Then i on 25th february i found 2 eggs. I dont know which of my cockatiel is laying egg. Both are always staying inside coming out only 3 times a day. But while coming out i saw they both poops lot and they both having a bulge near their vent. So I am having doubt whether they both are females. If it is would two female cockatiels lay egg without female?. On today 28th february there must be 3 eggs. But I found 4 eggs. I am very much confused and worried whether they both or female? they both having bulge , which cockatiel is laying egg?
